#### Introduction

Back## Mathematics and Statistics

Professors R. Benedetto, Call, Folsom*, Horton, Leise**, and Wagaman**; Associate Professor Ching (Chair of Mathematics); Assistant Professors Alvarado, Bailey, Contreras, Correia, Culiuc*, Daniels, Liao, and Pflueger*; Senior Lecturer D. Benedetto; Lecturers Donges, Matheson, and Zhang; Visiting Professor Cox (Chair of Statistics); Visiting Assistant Professors Elliott, Moore, Rasheed, and van Wyk; Moss Quantitative Center Associate Director Allison Tanguay; Academic Department Coordinator Kathy Glista.

The Department offers the major in Mathematics and the major in Statistics, as well as courses meeting a wide variety of interests in these fields. Non-majors who seek introductory courses are advised to consider MATH 105, 111, 140, 150, and 220, and STAT 111, none of which require a background beyond high school mathematics.

**Mathematics**

*Major Program*. Mathematics majors must complete MATH 111, 121, 211, 271 or 272, 350, and 355. In place of MATH 111, majors may complete MATH 105 and 106. Along with the required courses, a major must complete three elective courses in Mathematics numbered between 135 and 490. At least two of these electives must be numbered 200 or higher. In addition, a major must complete two other courses, each of which is either an elective course in Mathematics numbered between 135 and 490 or a course from outside Mathematics, but in a related field, chosen from among COSC 211, 311, and 401; ECON 300, 301, 361, and 420; any Physics course numbered 116 or higher; any Astronomy course numbered 226 or higher; and any Statistics course numbered 200 or higher. Statistics courses cross-listed with Mathematics count as Mathematics electives. The additional requirement of two courses can be satisfied by taking two math electives, one math elective and one related-fields course, or two related-fields courses. Requests for alternative courses must be approved in writing by the chair of the Department in consultation with the Mathematics faculty within the Department. Honors students may petition the department to count one math thesis course as an elective toward the major.

Mathematics majors may not apply a Pass grade from a pass/fail option to any of the core courses required for the mathematics major: MATH 111, 121, 211, 271/272, 350, or 355 (exceptions by petition to the department). Pass grades may be applied to electives.

Students who have placed out of certain courses, such as calculus, as indicated by a strong performance on an Advanced Placement Exam or other evidence approved by the department are excused from taking those courses. Students who place out of MATH 111, 121, or 211, do not need to replace these courses. Students who place out of MATH 271/272 must replace them with an additional Mathematics course numbered 225 or higher. Students who place out of MATH 350 and/or 355 must replace each such course with an additional Mathematics course numbered 300 or higher.

A student considering a major in Mathematics should consult with a member of the Department as soon as possible, preferably during their first year. This will facilitate the arrangement of a program best suited to the student’s ability and interests. Students should also be aware that there is no single path through the major; courses do not have to be taken in numerical order (except where required by prerequisites).

To complement the abstract thinking and mathematical proof-writing skills in the core courses, students majoring in Mathematics are encouraged to include in their program courses that include concepts and methods from data analysis, mathematical modeling, and computation (e.g., MATH 135/STAT 135, MATH 140, MATH 284, MATH 360/STAT 360, or COSC 111). We also encourage all Mathematics majors to attend department colloquia to learn more about different areas of mathematics and engage in the larger mathematics community.

For a student considering graduate study, the Departmental Honors program is strongly recommended. Such a student is advised to take the Graduate Record Examination early in the senior year. It is also desirable to have a reading knowledge of a foreign language, usually French, German, or Russian.

*Double Majors in Mathematics and Statistics. *Students electing a double major in Mathematics and Statistics may count MATH 111 and MATH 121 towards both majors. A maximum of one additional course taken to complete the Statistics major may be counted towards the Mathematics major.

*Comprehensive Examination*. A comprehensive examination will be given near the beginning of the spring semester of the senior year. (Those who will complete their studies in the fall semester may elect instead to take the comprehensive examination at the beginning of that semester.) The examination covers MATH 211, MATH 271 or 272, and a choice of MATH 350 or 355. More information about the comprehensive examination, including regulations and study materials, can be found on the Department website.

*Honors Program in Mathematics*. Students are admitted to the Honors Program on the basis of a qualifying examination given at the beginning of the spring semester of their junior year and the acceptance of a thesis proposal. (Those for whom the second semester of the junior year occurs in the fall may elect instead to take the qualifying examination at the beginning of that semester.) If a student is accepted to the Honors Program, they will finalize a topic in consultation with Mathematics faculty. After intensive study of this topic, the candidate will write a report in the form of a thesis which should be original in its presentation of material, if not in content. In addition, the candidate will report to the departmental colloquium on their thesis work during the senior year. Honors candidates are also required to complete MATH 345 and at least one Mathematics course numbered 400 to 489.

** **

**Statistics**

*Major Program. *The minimum requirements for the Statistics major include MATH 111 and 121; STAT 111, 135, or 136 (STAT 135 or 136 strongly recommended); STAT 230, 231, 360, 370, and 495; and at least 4 elective courses from among groups A, B, and C below. The combination of elective courses counted towards the Statistics major must be one of the following:

- 3 courses from group A, and 1 course from group B;
- 2 courses from group A, and 2 courses from group B;
- 2 courses from group A, 1 course from group B, and 1 course from group C
- 1 course from group A, 2 courses from group B, and 1 course from group C.

The groups:

- Statistics courses numbered 200 or above (statistical breadth);
- Computer Science courses: COSC 111, COSC 112, COSC 211, COSC 311 (computing requirement);
- A course numbered 200 or above that has been approved by the department as part of a student’s declared domain application, or a course from the following list of pre-approved courses that supplement the statistics curriculum:

BIOL/CHEM 250, COSC 254, COSC 257, COSC 355, MATH 271, MATH 272, MATH 355, MATH 365.

Statistics majors are strongly encouraged to ensure that their course of study includes depth in a domain application (e.g., astronomy, environmental studies, political science, psychology, or sociology). Majors are encouraged to discuss with their academic advisor which courses might be approved as part of a domain application as described in group C.

Statistics majors may not apply a Pass grade from a pass/fail option to any of the core courses required for the statistics major: STAT 111/135/136, 230, 231, 360, 370, or 495 (exceptions by petition to the department).

Requests for alternative courses must be approved in writing by the Statistics faculty within the Department. Students may submit petitions for such courses via their advisors or by contacting the Department Chair. Students who have placed out of certain courses, such as calculus, introductory statistics, or introductory computer science, as indicated by strong performance on an Advanced Placement Exam or other evidence approved by the Department, are excused from taking those courses. Statistics majors may place out of up to three courses without having to replace those courses. Students placing out of more than three courses must replace all but three of those courses with additional courses approved by the Department to complete the major.

A student considering a major in Statistics should consult with a member of the Department as soon as possible, ideally during the first year. This will facilitate the arrangement of a program best suited to the student’s ability and interests, with plans to accommodate study away, if desired. Students should also be aware that there is no single path through the major; courses do not have to be taken in numerical order (except where required by prerequisites). Students majoring in Statistics are expected to attend all Statistics colloquia during their junior and senior years. Students planning to attend graduate school in statistics are strongly advised to take MATH 211, MATH 271 or 272, MATH 355, MATH 450, and additional courses with a focus on computation and algorithmic thinking (often found in computer science).

*Double majors in Mathematics and Statistics.* Note that for double majors, MATH 111, MATH 121, and at most one other course (usually MATH/STAT 360) can be counted towards both the Mathematics and Statistics majors. Aside from this permitted overlap, statistics, mathematics, or computer science courses counted towards the statistics major may not also be counted towards the mathematics major.

*Comprehensive Evaluation. *All Statistics majors will enroll in the capstone course STAT 495 (Advanced Data Analysis). Beginning with the class of 2021, successful completion of this course satisfies the comprehensive evaluation in Statistics.

*Honors Program in Statistics. *For a degree with Honors, a student must have demonstrated the ability to pursue independent work fruitfully and exhibit a strong motivation to engage in research. To apply to the Honors Program, students must have an average grade of B+ or higher in Statistics 230, 231, 360, and 370. Students are also expected to have completed STAT 370 before the first semester of thesis work is undertaken. E students interested in theses should plan accordingly. Students are admitted to the Honors Program on the basis of a thesis proposal which must be accepted by the department. More information about the Honors Program can be found on the Department website.

If a student is accepted to the Honors Program, they will finalize their topic in consultation with their assigned advisor. After intensive study of this topic (one thesis course during each semester of the senior year), the Honors candidate will write a report in the form of a thesis which should be original in its presentation of material, if not in content, which is then evaluated by the Statistics faculty. In addition, the candidate will give a 30-40 minute presentation of (some of) the material, followed by faculty questions. This presentation occurs during the second semester of the senior year.

Honors students must complete an additional course for the major. The course must be broadly related to the thesis (e.g., a statistics elective with an introduction to the topic; linear algebra for more theoretical theses; an advanced Computer Science course for more computational theses). The thesis advisor must approve the course as “related”. Mathematics and Statistics double majors should remember that only one course beyond calculus can count towards both majors.

### Mathematics

#### 105 Calculus with Algebra

MATH 105 and 106 are designed for students whose background and algebraic skills are inadequate for the fast pace of MATH 111. In addition to covering the usual material of beginning calculus, these courses will have an extensive review of algebra and trigonometry. There will be a special emphasis on solving word problems.

MATH 105 starts with a quick review of algebraic manipulations, inequalities, absolute values and straight lines. Then the basic ideas of calculus—limits, derivatives, and integrals—are introduced, but only in the context of polynomial and rational functions. As various applications are studied, the algebraic techniques involved will be reviewed in more detail. When covering related rates and maximum-minimum problems, time will be spent learning how to approach, analyze and solve word problems. Four class meetings per week, one of which is an 80-minute group-work day.

Note: While MATH 105 and 106 are sufficient for any course with a MATH 111 requisite, MATH 105 alone is not. However, students who plan to take MATH 121 should consider taking MATH 105 and then MATH 111, rather than MATH 106. Students cannot register for both MATH 105 and CHEM 151 in the same semester.

#### 135 Introduction to Statistics via Modeling

(Offered as STAT 135 and MATH 135) This course is an introductory statistics course that uses modeling as a unifying framework. The course provides a basic foundation in statistics with a major emphasis on constructing models from data. Students learn important concepts of statistics by mastering powerful and relatively advanced statistical techniques using computational tools. Topics include descriptive and inferential statistics, visualization, probability, study design, and multiple regression.

Students who have taken a semester of calculus (MATH 111 or higher, or equivalent placement) or who are majoring or planning to major in mathematics and/or statistics should take this course instead of STAT 111. (Students who have taken STAT 111, STAT136, or PSYC 122 may not also receive credit for STAT/MATH 135. Students who have taken ECON 360/361 will be admitted only with consent of the instructor.) No prior experience with statistical software is expected.

Requisite:

Student has completed or is in process of completing MATH 111 or has placement in MATH 121 or above, or has statistics placement of STAT135 or has consent of the instructor. Limited to 24 students per section. Fall and spring semesters. The Department.

#### 140 Mathematical Modeling

Mathematical modeling is the process of translating a real world problem into a mathematical expression, analyzing it using mathematical tools and numerical simulations, and then interpreting the results in the context of the original problem. Discussion of basic modeling principles and case studies will be followed by several projects from areas including biology and the social sciences (e.g., flocking and schooling behavior, disease spread in populations, generation of artificial societies). This course has no requisites; projects will be tailored to each student’s level of mathematical preparation. Four class hours per week, with occasional in-class computer labs.

Limited to 24 students. Spring semester. Professor Leise.

#### 150 Voting and Elections: A Mathematical Perspective

The outcomes of many elections, whether to elect the next United States president or to rank college football teams, can displease many of the voters. How can perfectly fair elections produce results that nobody likes? We will analyze different voting systems, including majority rule, plurality rule, Borda count, and approval voting, and assess a voter’s power to influence the election under each system, for example, by calculating the Banzhaf power index. We will prove Arrow’s Theorem and discuss its implications. After exploring the pitfalls of various voting systems through both theoretical analysis and case studies, we will try to answer some pressing questions: Which voting system best reflects the will of the voters? Which is least susceptible to manipulation? What properties should we seek in a voting system, and how can we best attain them?

Limited to 24 students. Omitted 2021-22.

**2022-23:**Offered in Fall 2022

#### 225 Fractal Geometry

This course is a mathematical treatment of fractal geometry, a field of mathematics partly developed by Benoit Mandelbrot (1924–2010) that continues to be actively researched in the present day. Fractal geometry is a mathematical examination of the concepts of self-similarity, fractals, and chaos, and their applications to the modeling of natural phenomena. In particular, we will develop the iterated function system (IFS) method for describing fractals, examine Julia sets, Mandelbrot sets, and study the concept of fractal dimension, among other things. Through the teaching of these concepts, the course will also lend itself to familiarizing students with some of the formalisms and rigor of mathematical proofs.

Requisite: MATH 211 or consent of the instructor. Limited to 35 students. Professor Folsom.

**2022-23:**Offered in Spring 2023

**Other years:**Offered in Spring 2024

#### 252 Mathematics of Public-Key Cryptography

Many security problems arise when two computers must communicate on a channel with eavesdroppers or malicious attackers. Public-key cryptography applies ideas from number theory and abstract algebra to address these problems. This course concerns the mathematical theory and algorithms needed to construct the most commonly-used public-key ciphers and digital signature schemes, as well as the attacks that must be anticipated when designing such systems. Several topics from number theory, abstract algebra, and algorithms will be introduced, including discrete logarithms, integer factorization algorithms, and elliptic curves. Depending on time and student interest, we may cover some newer systems that are believed to be secure against attacks by quantum computers but not yet commonly implemented in practice. Students will write short programs to implement the systems and to break badly implemented systems. No prior programming experience is expected; basic aspects of programming in Python will be taught in class. Four class hours per week.

Requisite: Experience writing proofs, such as MATH 220/221 or 271/272, or consent of the instructor. Spring semester. Professor Pflueger.

**2022-23:**Offered in Spring 2023

#### 275 A Second Course in Linear Algebra

This course is a continuation of the material in MATH 271 and 272, providing more insight into abstract vector spaces and operator theory. Topics may include least squares estimates, singular value decompositions, Jordan canonical forms, inner product spaces, linear functionals and duals, orthogonal polynomials, vector and matrix norms, the spectral theorem, eigenvalue inequalities, and error-correcting codes. Time permitting, applications to graph theory and discrete dynamical systems may be explored. Four class hours per week.

Requisites: MATH 271, MATH 272, or consent of the instructor. Spring semester. Limited to 25 students.

**2022-23:**Offered in Spring 2023

#### 280 Graph Theory

A graph is a collection of points with edges drawn between them. Graph theory was first introduced by Leonhard Euler in his solution to the Königsberg bridge problem in 1736. Since then, graph theory has become an active area of study in mathematics due both to its wide array of real life applications in biology, chemistry, social sciences and computer networking, and to its interactions with other branches of mathematics.

The course will start with an overview of the fundamental concepts and general results in graph theory, followed by explorations of a variety of topics in graph theory and their applications, including: connectivity, planar graphs, directed graphs, greedy algorithms, matchings, vertex and edge colorings. The course will end with the introduction of a more advanced topic. Four class hours per week.

Requisite: MATH 271 or 272 or consent of the instructor. MATH 220 or other prior experience with mathematical proofs is recommended. Limited to 30 students. Fall semester. Professor Contreras.

**2022-23:**Offered in Fall 2022

**Other years:**Offered in Fall 2022, Fall 2023

#### 294 Optimization

Optimization is a branch of applied mathematics focused on algorithms to determine maxima and minima of functions, often under constraints. Applications range from economics and finance to machine learning and information retrieval. This course will first develop advanced linear algebra tools, and then will study methods of convex optimization. Possible topics include linear, quadratic, second-order cone, and semidefinite models. Several applications will be explored, and algorithms will be implemented using mathematical software to aid numerical experimentation.

Requisite: MATH 211 and 271 or 272, or consent of the instructor. Limited to 30 students. Omitted 2021-22.

#### 360 Probability

(Offered as STAT 360 and MATH 360) This course explores the nature of probability and its use in modeling real world phenomena. There are two explicit complementary goals: to explore probability theory and its use in applied settings, and to learn parallel analytic and empirical problem-solving skills. The course begins with the development of an intuitive feel for probabilistic thinking, based on the simple yet subtle idea of counting. It then evolves toward the rigorous study of discrete and continuous probability spaces, independence, conditional probability, expectation, and variance. Distributions covered include the binomial, hypergeometric, Poisson, normal, Gamma, Beta, multinomial, and bivariate normal. Other topics include generating functions, order statistics, and limit theorems.

Requisite:

Student has completed or is in the process of completing MATH 121, or has MATH 211 placement, or has consent of the instructor. Limited to 24 students. Fall semester. Professor Horton.

#### 385 Mathematical Logic

Mathematicians confirm their answers to mathematical questions by writing proofs. But what, exactly, is a proof? This course begins with a precise definition specifying what counts as a mathematical proof. This definition makes it possible to carry out a mathematical study of what can be accomplished by means of deductive reasoning and, perhaps more interestingly, what cannot be accomplished. Topics will include the propositional and predicate calculi, completeness, compactness, and decidability. At the end of the course we will study Gödel’s famous Incompleteness Theorem, which shows that there are statements about the positive integers that are true but impossible to prove. Four class hours per week. Offered in alternate years.

Requisite: MATH 220, 271, 272, or 355, or consent of the instructor. Spring semester. Professor Ching.

#### 405 Lie Groups and Lie Algebras

Lie groups and Lie algebras appear naturally in the study of symmetries of geometric objects. Lie algebras carry local information and can be studied using tools from linear algebra. Finite dimensional Lie groups can be constructed using techniques from calculus and group theory.

This course serves as a first introduction to Lie groups and Lie algebras. We will examine the structure of finite dimensional matrix Lie groups, the exponential and differentiation maps, as well as compact Lie groups. We will also study Lie algebras, ideals and homomorphisms, nilpotent and solvable Lie algebras, Cartan subalgebras, semisimplicity and root systems, and the classification of semisimple Lie algebras. This classification is not only a fundamental result in Lie Theory, but is also an archetype of classifications that appear in other areas of math. More amazingly, this classification is embodied in simple combinatorial pictures called Dynkin diagrams, which underlie surprisingly disparate fields, such as geometric group theory, quiver representation theory, and string theory. Four class meetings per week.

Requisite: MATH 350 or consent of the instructor. Fall semester.

#### 410 Galois Theory

The quadratic formula shows us that the roots of a quadratic polynomial possess a certain symmetry. Galois Theory is the study of the corresponding symmetry for higher degree polynomials. We will develop this theory starting from a basic knowledge of groups, rings, and fields. One of our main goals will be to prove that there is no general version of the quadratic formula for a polynomial of degree five or more. Along the way, we will also show that a circular cake can be divided into 17 (but not 7) equal slices using only a straight-edged knife.

Requisite: MATH 350 or consent of the instructor. Spring semester. Prof. Daniels.

### Statistics

#### 108 Statistical Ethics and Institutions

(Offered as STAT 108 and ECON 108) This course will provide a rigorous presentation of fundamental statistical principles and ethics. We will discuss standards for relationships between statisticians and policymakers, researchers, the press, and other institutions, as well as the standards for interactions between statisticians and their employers/clients, colleagues and research subjects. The course will explore how the interplay of institutions (e.g., organizations, systems, laws, codes of professional ethics) and the broader sociopolitical culture affect the production of reliable, high quality statistics. Students will also explore the implications of statistical principles and ethics for the operation of national, regional, and international official statistical systems. In addition, we will investigate the proper place of official statistics within a government system that operates with separate branches. Students will gain a strong foundation in international statistical principles and professional ethics as well as an understanding and the tools to assess the quality of the statistics they use. The course is designed to make students responsible and effective supporters of reliable, high quality statistics in their professions. Students will particularly learn how to assess the quality of official statistics produced by governments and how to identify areas for improvement. Examples, case studies, readings from statistical practice, and discussion will provide a full appreciation of real world applications. The course is also intended for non-majors interested in an introduction to quantitative social science and the use of data in public policy.

Limited to 30 students. Visiting Scholar Andreas Georgiou.

#### 136 Exploring Mental Health Inequities via Statistics: Happy Intro Stats

This is an interactive course designed to help students understand inequities in mental health issues via statistics. We will begin the course by examining mental health stigmas and practice self-care exercises to train our “happy muscles” together. We will discover the scientific evidence behind those self-care practices and explore existing racial disparities in mental health care systems, while learning about important statistical concepts and mastering our data analysis skills using R (a popular statistical software package). Statistical topics covered include descriptive statistics, visualization, study design, simulation-based inferences, and multiple regression. Students are expected to play an active role in co-creating the course and co-building an inclusive learning community with their peers and the professor. Course components include weekly reading and discussion, regular self-reflections and problem sets, and collaborative work in groups. We will use an OER (Open-Educational-Resources) textbook in this course. No prior experience with statistical software is expected.

This course is an alternative to STAT135 (Introduction to Statistics via Modeling) with a special focus on mental health issues. Students may not receive credit for both this course and STAT 111, STAT 135, or PSYC122. Limited to 24 students.

**Other years:**Offered in Fall 2022, Fall 2023, Spring 2024

#### 240 Multivariate Data Analysis

Making sense of a complex, high-dimensional data set is not an easy task. The analysis chosen is ultimately based on the research question(s) being asked. This course will explore how to visualize and extract meaning from large data sets through a variety of analytical methods. Methods covered include principal components analysis and selected statistical and machine learning techniques, both supervised (e.g. classification trees and random forests) and unsupervised (e.g. clustering). Additional methods covered may include factor analysis, dimension reduction methods, or network analysis at instructor discretion. This course will feature hands-on data analysis with statistical software, emphasizing application over theory.

The course is expected to include small group work, interactive labs, peer interactions such as peer review and short presentations, and a personal project, to foster student engagement in the course and with each other.

#### 375 Statistical Aspects of Competition

Competitions, which can include individual and team sports, eSports, tabletop gaming, preference formation, and elections, produce data dependent on interrelated competitors and the decision, league, or tournament format. In this course, students will learn to think about the ways a wide variety of statistical methodologies can be applied to the complex and unique data that emerge through competition, including paired comparisons, decision analysis, rank-based and kernel methods, and spatio-temporal methods. The course will focus on the statistical theory relevant to analyzing data from contests and place an emphasis on simulation and data visualization techniques. Students will develop data collection, wrangling,combination, exploration, analysis, and interpretation skills individually and in groups. Applications may include rating players and teams, assessing shot quality, animating player tracking data, roster construction, comparing alternative voting systems, developing optimal strategies for games, and predicting outcomes. Prior experience with probability such as STAT 360 may be helpful, but is not required.

Requisite: STAT 230 and STAT 231. Limited to 24 students. Fall semester. Professor McShane.

#### 495 Advanced Data Analysis

Our world is awash in data. To allow decisions to be made based on evidence, there is a need for statisticians to be able to make sense of the data around us and communicate their findings. In this course, students will be exposed to advanced statistical methods and will undertake the analysis and interpretation of complex and real-world datasets that go beyond textbook problems. Course topics will vary from year to year depending on the instructor and selected case studies but will include static and dynamic visualization techniques to summarize and display high dimensional data, advanced topics in design and linear regression, ethics, and selected topics in data mining. Other topics may vary but might include nonparametric analysis, spatial data, and analysis of network data. Through a series of case studies, students will develop the capacity to think and compute with data, undertake and assess analyses, and effectively communicate their results using written and oral presentation.

Back## Mathematics and Statistics

Professors R. Benedetto, Call, Folsom*, Horton, Leise**, and Wagaman**; Associate Professor Ching (Chair of Mathematics); Assistant Professors Alvarado, Bailey, Contreras, Correia, Culiuc*, Daniels, Liao, and Pflueger*; Senior Lecturer D. Benedetto; Lecturers Donges, Matheson, and Zhang; Visiting Professor Cox (Chair of Statistics); Visiting Assistant Professors Elliott, Moore, Rasheed, and van Wyk; Moss Quantitative Center Associate Director Allison Tanguay; Academic Department Coordinator Kathy Glista.

The Department offers the major in Mathematics and the major in Statistics, as well as courses meeting a wide variety of interests in these fields. Non-majors who seek introductory courses are advised to consider MATH 105, 111, 140, 150, and 220, and STAT 111, none of which require a background beyond high school mathematics.

**Mathematics**

*Major Program*. Mathematics majors must complete MATH 111, 121, 211, 271 or 272, 350, and 355. In place of MATH 111, majors may complete MATH 105 and 106. Along with the required courses, a major must complete three elective courses in Mathematics numbered between 135 and 490. At least two of these electives must be numbered 200 or higher. In addition, a major must complete two other courses, each of which is either an elective course in Mathematics numbered between 135 and 490 or a course from outside Mathematics, but in a related field, chosen from among COSC 211, 311, and 401; ECON 300, 301, 361, and 420; any Physics course numbered 116 or higher; any Astronomy course numbered 226 or higher; and any Statistics course numbered 200 or higher. Statistics courses cross-listed with Mathematics count as Mathematics electives. The additional requirement of two courses can be satisfied by taking two math electives, one math elective and one related-fields course, or two related-fields courses. Requests for alternative courses must be approved in writing by the chair of the Department in consultation with the Mathematics faculty within the Department. Honors students may petition the department to count one math thesis course as an elective toward the major.

Mathematics majors may not apply a Pass grade from a pass/fail option to any of the core courses required for the mathematics major: MATH 111, 121, 211, 271/272, 350, or 355 (exceptions by petition to the department). Pass grades may be applied to electives.

Students who have placed out of certain courses, such as calculus, as indicated by a strong performance on an Advanced Placement Exam or other evidence approved by the department are excused from taking those courses. Students who place out of MATH 111, 121, or 211, do not need to replace these courses. Students who place out of MATH 271/272 must replace them with an additional Mathematics course numbered 225 or higher. Students who place out of MATH 350 and/or 355 must replace each such course with an additional Mathematics course numbered 300 or higher.

A student considering a major in Mathematics should consult with a member of the Department as soon as possible, preferably during their first year. This will facilitate the arrangement of a program best suited to the student’s ability and interests. Students should also be aware that there is no single path through the major; courses do not have to be taken in numerical order (except where required by prerequisites).

To complement the abstract thinking and mathematical proof-writing skills in the core courses, students majoring in Mathematics are encouraged to include in their program courses that include concepts and methods from data analysis, mathematical modeling, and computation (e.g., MATH 135/STAT 135, MATH 140, MATH 284, MATH 360/STAT 360, or COSC 111). We also encourage all Mathematics majors to attend department colloquia to learn more about different areas of mathematics and engage in the larger mathematics community.

For a student considering graduate study, the Departmental Honors program is strongly recommended. Such a student is advised to take the Graduate Record Examination early in the senior year. It is also desirable to have a reading knowledge of a foreign language, usually French, German, or Russian.

*Double Majors in Mathematics and Statistics. *Students electing a double major in Mathematics and Statistics may count MATH 111 and MATH 121 towards both majors. A maximum of one additional course taken to complete the Statistics major may be counted towards the Mathematics major.

*Comprehensive Examination*. A comprehensive examination will be given near the beginning of the spring semester of the senior year. (Those who will complete their studies in the fall semester may elect instead to take the comprehensive examination at the beginning of that semester.) The examination covers MATH 211, MATH 271 or 272, and a choice of MATH 350 or 355. More information about the comprehensive examination, including regulations and study materials, can be found on the Department website.

*Honors Program in Mathematics*. Students are admitted to the Honors Program on the basis of a qualifying examination given at the beginning of the spring semester of their junior year and the acceptance of a thesis proposal. (Those for whom the second semester of the junior year occurs in the fall may elect instead to take the qualifying examination at the beginning of that semester.) If a student is accepted to the Honors Program, they will finalize a topic in consultation with Mathematics faculty. After intensive study of this topic, the candidate will write a report in the form of a thesis which should be original in its presentation of material, if not in content. In addition, the candidate will report to the departmental colloquium on their thesis work during the senior year. Honors candidates are also required to complete MATH 345 and at least one Mathematics course numbered 400 to 489.

** **

**Statistics**

*Major Program. *The minimum requirements for the Statistics major include MATH 111 and 121; STAT 111, 135, or 136 (STAT 135 or 136 strongly recommended); STAT 230, 231, 360, 370, and 495; and at least 4 elective courses from among groups A, B, and C below. The combination of elective courses counted towards the Statistics major must be one of the following:

- 3 courses from group A, and 1 course from group B;
- 2 courses from group A, and 2 courses from group B;
- 2 courses from group A, 1 course from group B, and 1 course from group C
- 1 course from group A, 2 courses from group B, and 1 course from group C.

The groups:

- Statistics courses numbered 200 or above (statistical breadth);
- Computer Science courses: COSC 111, COSC 112, COSC 211, COSC 311 (computing requirement);
- A course numbered 200 or above that has been approved by the department as part of a student’s declared domain application, or a course from the following list of pre-approved courses that supplement the statistics curriculum:

BIOL/CHEM 250, COSC 254, COSC 257, COSC 355, MATH 271, MATH 272, MATH 355, MATH 365.

Statistics majors are strongly encouraged to ensure that their course of study includes depth in a domain application (e.g., astronomy, environmental studies, political science, psychology, or sociology). Majors are encouraged to discuss with their academic advisor which courses might be approved as part of a domain application as described in group C.

Statistics majors may not apply a Pass grade from a pass/fail option to any of the core courses required for the statistics major: STAT 111/135/136, 230, 231, 360, 370, or 495 (exceptions by petition to the department).

Requests for alternative courses must be approved in writing by the Statistics faculty within the Department. Students may submit petitions for such courses via their advisors or by contacting the Department Chair. Students who have placed out of certain courses, such as calculus, introductory statistics, or introductory computer science, as indicated by strong performance on an Advanced Placement Exam or other evidence approved by the Department, are excused from taking those courses. Statistics majors may place out of up to three courses without having to replace those courses. Students placing out of more than three courses must replace all but three of those courses with additional courses approved by the Department to complete the major.

A student considering a major in Statistics should consult with a member of the Department as soon as possible, ideally during the first year. This will facilitate the arrangement of a program best suited to the student’s ability and interests, with plans to accommodate study away, if desired. Students should also be aware that there is no single path through the major; courses do not have to be taken in numerical order (except where required by prerequisites). Students majoring in Statistics are expected to attend all Statistics colloquia during their junior and senior years. Students planning to attend graduate school in statistics are strongly advised to take MATH 211, MATH 271 or 272, MATH 355, MATH 450, and additional courses with a focus on computation and algorithmic thinking (often found in computer science).

*Double majors in Mathematics and Statistics.* Note that for double majors, MATH 111, MATH 121, and at most one other course (usually MATH/STAT 360) can be counted towards both the Mathematics and Statistics majors. Aside from this permitted overlap, statistics, mathematics, or computer science courses counted towards the statistics major may not also be counted towards the mathematics major.

*Comprehensive Evaluation. *All Statistics majors will enroll in the capstone course STAT 495 (Advanced Data Analysis). Beginning with the class of 2021, successful completion of this course satisfies the comprehensive evaluation in Statistics.

*Honors Program in Statistics. *For a degree with Honors, a student must have demonstrated the ability to pursue independent work fruitfully and exhibit a strong motivation to engage in research. To apply to the Honors Program, students must have an average grade of B+ or higher in Statistics 230, 231, 360, and 370. Students are also expected to have completed STAT 370 before the first semester of thesis work is undertaken. E students interested in theses should plan accordingly. Students are admitted to the Honors Program on the basis of a thesis proposal which must be accepted by the department. More information about the Honors Program can be found on the Department website.

If a student is accepted to the Honors Program, they will finalize their topic in consultation with their assigned advisor. After intensive study of this topic (one thesis course during each semester of the senior year), the Honors candidate will write a report in the form of a thesis which should be original in its presentation of material, if not in content, which is then evaluated by the Statistics faculty. In addition, the candidate will give a 30-40 minute presentation of (some of) the material, followed by faculty questions. This presentation occurs during the second semester of the senior year.

Honors students must complete an additional course for the major. The course must be broadly related to the thesis (e.g., a statistics elective with an introduction to the topic; linear algebra for more theoretical theses; an advanced Computer Science course for more computational theses). The thesis advisor must approve the course as “related”. Mathematics and Statistics double majors should remember that only one course beyond calculus can count towards both majors.

### Mathematics

#### 105 Calculus with Algebra

MATH 105 and 106 are designed for students whose background and algebraic skills are inadequate for the fast pace of MATH 111. In addition to covering the usual material of beginning calculus, these courses will have an extensive review of algebra and trigonometry. There will be a special emphasis on solving word problems.

MATH 105 starts with a quick review of algebraic manipulations, inequalities, absolute values and straight lines. Then the basic ideas of calculus—limits, derivatives, and integrals—are introduced, but only in the context of polynomial and rational functions. As various applications are studied, the algebraic techniques involved will be reviewed in more detail. When covering related rates and maximum-minimum problems, time will be spent learning how to approach, analyze and solve word problems. Four class meetings per week, one of which is an 80-minute group-work day.

Note: While MATH 105 and 106 are sufficient for any course with a MATH 111 requisite, MATH 105 alone is not. However, students who plan to take MATH 121 should consider taking MATH 105 and then MATH 111, rather than MATH 106. Students cannot register for both MATH 105 and CHEM 151 in the same semester.

#### 150 Voting and Elections: A Mathematical Perspective

The outcomes of many elections, whether to elect the next United States president or to rank college football teams, can displease many of the voters. How can perfectly fair elections produce results that nobody likes? We will analyze different voting systems, including majority rule, plurality rule, Borda count, and approval voting, and assess a voter’s power to influence the election under each system, for example, by calculating the Banzhaf power index. We will prove Arrow’s Theorem and discuss its implications. After exploring the pitfalls of various voting systems through both theoretical analysis and case studies, we will try to answer some pressing questions: Which voting system best reflects the will of the voters? Which is least susceptible to manipulation? What properties should we seek in a voting system, and how can we best attain them?

#### 225 Fractal Geometry

This course is a mathematical treatment of fractal geometry, a field of mathematics partly developed by Benoit Mandelbrot (1924–2010) that continues to be actively researched in the present day. Fractal geometry is a mathematical examination of the concepts of self-similarity, fractals, and chaos, and their applications to the modeling of natural phenomena. In particular, we will develop the iterated function system (IFS) method for describing fractals, examine Julia sets, Mandelbrot sets, and study the concept of fractal dimension, among other things. Through the teaching of these concepts, the course will also lend itself to familiarizing students with some of the formalisms and rigor of mathematical proofs.

#### 252 Mathematics of Public-Key Cryptography

Many security problems arise when two computers must communicate on a channel with eavesdroppers or malicious attackers. Public-key cryptography applies ideas from number theory and abstract algebra to address these problems. This course concerns the mathematical theory and algorithms needed to construct the most commonly-used public-key ciphers and digital signature schemes, as well as the attacks that must be anticipated when designing such systems. Several topics from number theory, abstract algebra, and algorithms will be introduced, including discrete logarithms, integer factorization algorithms, and elliptic curves. Depending on time and student interest, we may cover some newer systems that are believed to be secure against attacks by quantum computers but not yet commonly implemented in practice. Students will write short programs to implement the systems and to break badly implemented systems. No prior programming experience is expected; basic aspects of programming in Python will be taught in class. Four class hours per week.

#### 360 Probability

(Offered as STAT 360 and MATH 360) This course explores the nature of probability and its use in modeling real world phenomena. There are two explicit complementary goals: to explore probability theory and its use in applied settings, and to learn parallel analytic and empirical problem-solving skills. The course begins with the development of an intuitive feel for probabilistic thinking, based on the simple yet subtle idea of counting. It then evolves toward the rigorous study of discrete and continuous probability spaces, independence, conditional probability, expectation, and variance. Distributions covered include the binomial, hypergeometric, Poisson, normal, Gamma, Beta, multinomial, and bivariate normal. Other topics include generating functions, order statistics, and limit theorems.

Requisite:

Student has completed or is in the process of completing MATH 121, or has MATH 211 placement, or has consent of the instructor. Limited to 24 students. Fall semester. Professor Horton.

#### 385 Mathematical Logic

Mathematicians confirm their answers to mathematical questions by writing proofs. But what, exactly, is a proof? This course begins with a precise definition specifying what counts as a mathematical proof. This definition makes it possible to carry out a mathematical study of what can be accomplished by means of deductive reasoning and, perhaps more interestingly, what cannot be accomplished. Topics will include the propositional and predicate calculi, completeness, compactness, and decidability. At the end of the course we will study Gödel’s famous Incompleteness Theorem, which shows that there are statements about the positive integers that are true but impossible to prove. Four class hours per week. Offered in alternate years.

Requisite: MATH 220, 271, 272, or 355, or consent of the instructor. Spring semester. Professor Ching.

#### 405 Lie Groups and Lie Algebras

Lie groups and Lie algebras appear naturally in the study of symmetries of geometric objects. Lie algebras carry local information and can be studied using tools from linear algebra. Finite dimensional Lie groups can be constructed using techniques from calculus and group theory.

This course serves as a first introduction to Lie groups and Lie algebras. We will examine the structure of finite dimensional matrix Lie groups, the exponential and differentiation maps, as well as compact Lie groups. We will also study Lie algebras, ideals and homomorphisms, nilpotent and solvable Lie algebras, Cartan subalgebras, semisimplicity and root systems, and the classification of semisimple Lie algebras. This classification is not only a fundamental result in Lie Theory, but is also an archetype of classifications that appear in other areas of math. More amazingly, this classification is embodied in simple combinatorial pictures called Dynkin diagrams, which underlie surprisingly disparate fields, such as geometric group theory, quiver representation theory, and string theory. Four class meetings per week.

Requisite: MATH 350 or consent of the instructor. Fall semester.

#### 410 Galois Theory

The quadratic formula shows us that the roots of a quadratic polynomial possess a certain symmetry. Galois Theory is the study of the corresponding symmetry for higher degree polynomials. We will develop this theory starting from a basic knowledge of groups, rings, and fields. One of our main goals will be to prove that there is no general version of the quadratic formula for a polynomial of degree five or more. Along the way, we will also show that a circular cake can be divided into 17 (but not 7) equal slices using only a straight-edged knife.

### Statistics

#### 108 Statistical Ethics and Institutions

(Offered as STAT 108 and ECON 108) This course will provide a rigorous presentation of fundamental statistical principles and ethics. We will discuss standards for relationships between statisticians and policymakers, researchers, the press, and other institutions, as well as the standards for interactions between statisticians and their employers/clients, colleagues and research subjects. The course will explore how the interplay of institutions (e.g., organizations, systems, laws, codes of professional ethics) and the broader sociopolitical culture affect the production of reliable, high quality statistics. Students will also explore the implications of statistical principles and ethics for the operation of national, regional, and international official statistical systems. In addition, we will investigate the proper place of official statistics within a government system that operates with separate branches. Students will gain a strong foundation in international statistical principles and professional ethics as well as an understanding and the tools to assess the quality of the statistics they use. The course is designed to make students responsible and effective supporters of reliable, high quality statistics in their professions. Students will particularly learn how to assess the quality of official statistics produced by governments and how to identify areas for improvement. Examples, case studies, readings from statistical practice, and discussion will provide a full appreciation of real world applications. The course is also intended for non-majors interested in an introduction to quantitative social science and the use of data in public policy.

#### 136 Exploring Mental Health Inequities via Statistics: Happy Intro Stats

This is an interactive course designed to help students understand inequities in mental health issues via statistics. We will begin the course by examining mental health stigmas and practice self-care exercises to train our “happy muscles” together. We will discover the scientific evidence behind those self-care practices and explore existing racial disparities in mental health care systems, while learning about important statistical concepts and mastering our data analysis skills using R (a popular statistical software package). Statistical topics covered include descriptive statistics, visualization, study design, simulation-based inferences, and multiple regression. Students are expected to play an active role in co-creating the course and co-building an inclusive learning community with their peers and the professor. Course components include weekly reading and discussion, regular self-reflections and problem sets, and collaborative work in groups. We will use an OER (Open-Educational-Resources) textbook in this course. No prior experience with statistical software is expected.

This course is an alternative to STAT135 (Introduction to Statistics via Modeling) with a special focus on mental health issues. Students may not receive credit for both this course and STAT 111, STAT 135, or PSYC122. Limited to 24 students.

#### 240 Multivariate Data Analysis

Making sense of a complex, high-dimensional data set is not an easy task. The analysis chosen is ultimately based on the research question(s) being asked. This course will explore how to visualize and extract meaning from large data sets through a variety of analytical methods. Methods covered include principal components analysis and selected statistical and machine learning techniques, both supervised (e.g. classification trees and random forests) and unsupervised (e.g. clustering). Additional methods covered may include factor analysis, dimension reduction methods, or network analysis at instructor discretion. This course will feature hands-on data analysis with statistical software, emphasizing application over theory.

The course is expected to include small group work, interactive labs, peer interactions such as peer review and short presentations, and a personal project, to foster student engagement in the course and with each other.

#### 375 Statistical Aspects of Competition

Competitions, which can include individual and team sports, eSports, tabletop gaming, preference formation, and elections, produce data dependent on interrelated competitors and the decision, league, or tournament format. In this course, students will learn to think about the ways a wide variety of statistical methodologies can be applied to the complex and unique data that emerge through competition, including paired comparisons, decision analysis, rank-based and kernel methods, and spatio-temporal methods. The course will focus on the statistical theory relevant to analyzing data from contests and place an emphasis on simulation and data visualization techniques. Students will develop data collection, wrangling,combination, exploration, analysis, and interpretation skills individually and in groups. Applications may include rating players and teams, assessing shot quality, animating player tracking data, roster construction, comparing alternative voting systems, developing optimal strategies for games, and predicting outcomes. Prior experience with probability such as STAT 360 may be helpful, but is not required.

Requisite: STAT 230 and STAT 231. Limited to 24 students. Fall semester. Professor McShane.

#### 495 Advanced Data Analysis

Our world is awash in data. To allow decisions to be made based on evidence, there is a need for statisticians to be able to make sense of the data around us and communicate their findings. In this course, students will be exposed to advanced statistical methods and will undertake the analysis and interpretation of complex and real-world datasets that go beyond textbook problems. Course topics will vary from year to year depending on the instructor and selected case studies but will include static and dynamic visualization techniques to summarize and display high dimensional data, advanced topics in design and linear regression, ethics, and selected topics in data mining. Other topics may vary but might include nonparametric analysis, spatial data, and analysis of network data. Through a series of case studies, students will develop the capacity to think and compute with data, undertake and assess analyses, and effectively communicate their results using written and oral presentation.

Back## Mathematics and Statistics

Professors R. Benedetto, Call, Folsom*, Horton, Leise**, and Wagaman**; Associate Professor Ching (Chair of Mathematics); Assistant Professors Alvarado, Bailey, Contreras, Correia, Culiuc*, Daniels, Liao, and Pflueger*; Senior Lecturer D. Benedetto; Lecturers Donges, Matheson, and Zhang; Visiting Professor Cox (Chair of Statistics); Visiting Assistant Professors Elliott, Moore, Rasheed, and van Wyk; Moss Quantitative Center Associate Director Allison Tanguay; Academic Department Coordinator Kathy Glista.

The Department offers the major in Mathematics and the major in Statistics, as well as courses meeting a wide variety of interests in these fields. Non-majors who seek introductory courses are advised to consider MATH 105, 111, 140, 150, and 220, and STAT 111, none of which require a background beyond high school mathematics.

**Mathematics**

*Major Program*. Mathematics majors must complete MATH 111, 121, 211, 271 or 272, 350, and 355. In place of MATH 111, majors may complete MATH 105 and 106. Along with the required courses, a major must complete three elective courses in Mathematics numbered between 135 and 490. At least two of these electives must be numbered 200 or higher. In addition, a major must complete two other courses, each of which is either an elective course in Mathematics numbered between 135 and 490 or a course from outside Mathematics, but in a related field, chosen from among COSC 211, 311, and 401; ECON 300, 301, 361, and 420; any Physics course numbered 116 or higher; any Astronomy course numbered 226 or higher; and any Statistics course numbered 200 or higher. Statistics courses cross-listed with Mathematics count as Mathematics electives. The additional requirement of two courses can be satisfied by taking two math electives, one math elective and one related-fields course, or two related-fields courses. Requests for alternative courses must be approved in writing by the chair of the Department in consultation with the Mathematics faculty within the Department. Honors students may petition the department to count one math thesis course as an elective toward the major.

Mathematics majors may not apply a Pass grade from a pass/fail option to any of the core courses required for the mathematics major: MATH 111, 121, 211, 271/272, 350, or 355 (exceptions by petition to the department). Pass grades may be applied to electives.

Students who have placed out of certain courses, such as calculus, as indicated by a strong performance on an Advanced Placement Exam or other evidence approved by the department are excused from taking those courses. Students who place out of MATH 111, 121, or 211, do not need to replace these courses. Students who place out of MATH 271/272 must replace them with an additional Mathematics course numbered 225 or higher. Students who place out of MATH 350 and/or 355 must replace each such course with an additional Mathematics course numbered 300 or higher.

A student considering a major in Mathematics should consult with a member of the Department as soon as possible, preferably during their first year. This will facilitate the arrangement of a program best suited to the student’s ability and interests. Students should also be aware that there is no single path through the major; courses do not have to be taken in numerical order (except where required by prerequisites).

To complement the abstract thinking and mathematical proof-writing skills in the core courses, students majoring in Mathematics are encouraged to include in their program courses that include concepts and methods from data analysis, mathematical modeling, and computation (e.g., MATH 135/STAT 135, MATH 140, MATH 284, MATH 360/STAT 360, or COSC 111). We also encourage all Mathematics majors to attend department colloquia to learn more about different areas of mathematics and engage in the larger mathematics community.

For a student considering graduate study, the Departmental Honors program is strongly recommended. Such a student is advised to take the Graduate Record Examination early in the senior year. It is also desirable to have a reading knowledge of a foreign language, usually French, German, or Russian.

*Double Majors in Mathematics and Statistics. *Students electing a double major in Mathematics and Statistics may count MATH 111 and MATH 121 towards both majors. A maximum of one additional course taken to complete the Statistics major may be counted towards the Mathematics major.

*Comprehensive Examination*. A comprehensive examination will be given near the beginning of the spring semester of the senior year. (Those who will complete their studies in the fall semester may elect instead to take the comprehensive examination at the beginning of that semester.) The examination covers MATH 211, MATH 271 or 272, and a choice of MATH 350 or 355. More information about the comprehensive examination, including regulations and study materials, can be found on the Department website.

*Honors Program in Mathematics*. Students are admitted to the Honors Program on the basis of a qualifying examination given at the beginning of the spring semester of their junior year and the acceptance of a thesis proposal. (Those for whom the second semester of the junior year occurs in the fall may elect instead to take the qualifying examination at the beginning of that semester.) If a student is accepted to the Honors Program, they will finalize a topic in consultation with Mathematics faculty. After intensive study of this topic, the candidate will write a report in the form of a thesis which should be original in its presentation of material, if not in content. In addition, the candidate will report to the departmental colloquium on their thesis work during the senior year. Honors candidates are also required to complete MATH 345 and at least one Mathematics course numbered 400 to 489.

** **

**Statistics**

*Major Program. *The minimum requirements for the Statistics major include MATH 111 and 121; STAT 111, 135, or 136 (STAT 135 or 136 strongly recommended); STAT 230, 231, 360, 370, and 495; and at least 4 elective courses from among groups A, B, and C below. The combination of elective courses counted towards the Statistics major must be one of the following:

- 3 courses from group A, and 1 course from group B;
- 2 courses from group A, and 2 courses from group B;
- 2 courses from group A, 1 course from group B, and 1 course from group C
- 1 course from group A, 2 courses from group B, and 1 course from group C.

The groups:

- Statistics courses numbered 200 or above (statistical breadth);
- Computer Science courses: COSC 111, COSC 112, COSC 211, COSC 311 (computing requirement);
- A course numbered 200 or above that has been approved by the department as part of a student’s declared domain application, or a course from the following list of pre-approved courses that supplement the statistics curriculum:

BIOL/CHEM 250, COSC 254, COSC 257, COSC 355, MATH 271, MATH 272, MATH 355, MATH 365.

Statistics majors are strongly encouraged to ensure that their course of study includes depth in a domain application (e.g., astronomy, environmental studies, political science, psychology, or sociology). Majors are encouraged to discuss with their academic advisor which courses might be approved as part of a domain application as described in group C.

Statistics majors may not apply a Pass grade from a pass/fail option to any of the core courses required for the statistics major: STAT 111/135/136, 230, 231, 360, 370, or 495 (exceptions by petition to the department).

Requests for alternative courses must be approved in writing by the Statistics faculty within the Department. Students may submit petitions for such courses via their advisors or by contacting the Department Chair. Students who have placed out of certain courses, such as calculus, introductory statistics, or introductory computer science, as indicated by strong performance on an Advanced Placement Exam or other evidence approved by the Department, are excused from taking those courses. Statistics majors may place out of up to three courses without having to replace those courses. Students placing out of more than three courses must replace all but three of those courses with additional courses approved by the Department to complete the major.

A student considering a major in Statistics should consult with a member of the Department as soon as possible, ideally during the first year. This will facilitate the arrangement of a program best suited to the student’s ability and interests, with plans to accommodate study away, if desired. Students should also be aware that there is no single path through the major; courses do not have to be taken in numerical order (except where required by prerequisites). Students majoring in Statistics are expected to attend all Statistics colloquia during their junior and senior years. Students planning to attend graduate school in statistics are strongly advised to take MATH 211, MATH 271 or 272, MATH 355, MATH 450, and additional courses with a focus on computation and algorithmic thinking (often found in computer science).

*Double majors in Mathematics and Statistics.* Note that for double majors, MATH 111, MATH 121, and at most one other course (usually MATH/STAT 360) can be counted towards both the Mathematics and Statistics majors. Aside from this permitted overlap, statistics, mathematics, or computer science courses counted towards the statistics major may not also be counted towards the mathematics major.

*Comprehensive Evaluation. *All Statistics majors will enroll in the capstone course STAT 495 (Advanced Data Analysis). Beginning with the class of 2021, successful completion of this course satisfies the comprehensive evaluation in Statistics.

*Honors Program in Statistics. *For a degree with Honors, a student must have demonstrated the ability to pursue independent work fruitfully and exhibit a strong motivation to engage in research. To apply to the Honors Program, students must have an average grade of B+ or higher in Statistics 230, 231, 360, and 370. Students are also expected to have completed STAT 370 before the first semester of thesis work is undertaken. E students interested in theses should plan accordingly. Students are admitted to the Honors Program on the basis of a thesis proposal which must be accepted by the department. More information about the Honors Program can be found on the Department website.

If a student is accepted to the Honors Program, they will finalize their topic in consultation with their assigned advisor. After intensive study of this topic (one thesis course during each semester of the senior year), the Honors candidate will write a report in the form of a thesis which should be original in its presentation of material, if not in content, which is then evaluated by the Statistics faculty. In addition, the candidate will give a 30-40 minute presentation of (some of) the material, followed by faculty questions. This presentation occurs during the second semester of the senior year.

Honors students must complete an additional course for the major. The course must be broadly related to the thesis (e.g., a statistics elective with an introduction to the topic; linear algebra for more theoretical theses; an advanced Computer Science course for more computational theses). The thesis advisor must approve the course as “related”. Mathematics and Statistics double majors should remember that only one course beyond calculus can count towards both majors.

### Mathematics

#### 105 Calculus with Algebra

MATH 105 and 106 are designed for students whose background and algebraic skills are inadequate for the fast pace of MATH 111. In addition to covering the usual material of beginning calculus, these courses will have an extensive review of algebra and trigonometry. There will be a special emphasis on solving word problems.

MATH 105 starts with a quick review of algebraic manipulations, inequalities, absolute values and straight lines. Then the basic ideas of calculus—limits, derivatives, and integrals—are introduced, but only in the context of polynomial and rational functions. As various applications are studied, the algebraic techniques involved will be reviewed in more detail. When covering related rates and maximum-minimum problems, time will be spent learning how to approach, analyze and solve word problems. Four class meetings per week, one of which is an 80-minute group-work day.

Note: While MATH 105 and 106 are sufficient for any course with a MATH 111 requisite, MATH 105 alone is not. However, students who plan to take MATH 121 should consider taking MATH 105 and then MATH 111, rather than MATH 106. Students cannot register for both MATH 105 and CHEM 151 in the same semester.

#### 135 Introduction to Statistics via Modeling

(Offered as STAT 135 and MATH 135) This course is an introductory statistics course that uses modeling as a unifying framework. The course provides a basic foundation in statistics with a major emphasis on constructing models from data. Students learn important concepts of statistics by mastering powerful and relatively advanced statistical techniques using computational tools. Topics include descriptive and inferential statistics, visualization, probability, study design, and multiple regression.

Students who have taken a semester of calculus (MATH 111 or higher, or equivalent placement) or who are majoring or planning to major in mathematics and/or statistics should take this course instead of STAT 111. (Students who have taken STAT 111, STAT136, or PSYC 122 may not also receive credit for STAT/MATH 135. Students who have taken ECON 360/361 will be admitted only with consent of the instructor.) No prior experience with statistical software is expected.

Requisite:

Student has completed or is in process of completing MATH 111 or has placement in MATH 121 or above, or has statistics placement of STAT135 or has consent of the instructor. Limited to 24 students per section. Fall and spring semesters. The Department.

#### 140 Mathematical Modeling

Mathematical modeling is the process of translating a real world problem into a mathematical expression, analyzing it using mathematical tools and numerical simulations, and then interpreting the results in the context of the original problem. Discussion of basic modeling principles and case studies will be followed by several projects from areas including biology and the social sciences (e.g., flocking and schooling behavior, disease spread in populations, generation of artificial societies). This course has no requisites; projects will be tailored to each student’s level of mathematical preparation. Four class hours per week, with occasional in-class computer labs.

Limited to 24 students. Spring semester. Professor Leise.

#### 150 Voting and Elections: A Mathematical Perspective

The outcomes of many elections, whether to elect the next United States president or to rank college football teams, can displease many of the voters. How can perfectly fair elections produce results that nobody likes? We will analyze different voting systems, including majority rule, plurality rule, Borda count, and approval voting, and assess a voter’s power to influence the election under each system, for example, by calculating the Banzhaf power index. We will prove Arrow’s Theorem and discuss its implications. After exploring the pitfalls of various voting systems through both theoretical analysis and case studies, we will try to answer some pressing questions: Which voting system best reflects the will of the voters? Which is least susceptible to manipulation? What properties should we seek in a voting system, and how can we best attain them?

Limited to 24 students. Omitted 2021-22.

#### 225 Fractal Geometry

This course is a mathematical treatment of fractal geometry, a field of mathematics partly developed by Benoit Mandelbrot (1924–2010) that continues to be actively researched in the present day. Fractal geometry is a mathematical examination of the concepts of self-similarity, fractals, and chaos, and their applications to the modeling of natural phenomena. In particular, we will develop the iterated function system (IFS) method for describing fractals, examine Julia sets, Mandelbrot sets, and study the concept of fractal dimension, among other things. Through the teaching of these concepts, the course will also lend itself to familiarizing students with some of the formalisms and rigor of mathematical proofs.

Requisite: MATH 211 or consent of the instructor. Limited to 35 students. Professor Folsom.

**2022-23:**Offered in Spring 2023

**Other years:**Offered in Spring 2024

#### 250 Number Theory

#### 252 Mathematics of Public-Key Cryptography

Many security problems arise when two computers must communicate on a channel with eavesdroppers or malicious attackers. Public-key cryptography applies ideas from number theory and abstract algebra to address these problems. This course concerns the mathematical theory and algorithms needed to construct the most commonly-used public-key ciphers and digital signature schemes, as well as the attacks that must be anticipated when designing such systems. Several topics from number theory, abstract algebra, and algorithms will be introduced, including discrete logarithms, integer factorization algorithms, and elliptic curves. Depending on time and student interest, we may cover some newer systems that are believed to be secure against attacks by quantum computers but not yet commonly implemented in practice. Students will write short programs to implement the systems and to break badly implemented systems. No prior programming experience is expected; basic aspects of programming in Python will be taught in class. Four class hours per week.

Requisite: Experience writing proofs, such as MATH 220/221 or 271/272, or consent of the instructor. Spring semester. Professor Pflueger.

**2022-23:**Offered in Spring 2023

Mathematicians confirm their answers to mathematical questions by writing proofs. But what, exactly, is a proof? This course begins with a precise definition specifying what counts as a mathematical proof. This definition makes it possible to carry out a mathematical study of what can be accomplished by means of deductive reasoning and, perhaps more interestingly, what cannot be accomplished. Topics will include the propositional and predicate calculi, completeness, compactness, and decidability. At the end of the course we will study Gödel’s famous Incompleteness Theorem, which shows that there are statements about the positive integers that are true but impossible to prove. Four class hours per week. Offered in alternate years.

#### 405 Lie Groups and Lie Algebras

Lie groups and Lie algebras appear naturally in the study of symmetries of geometric objects. Lie algebras carry local information and can be studied using tools from linear algebra. Finite dimensional Lie groups can be constructed using techniques from calculus and group theory.

This course serves as a first introduction to Lie groups and Lie algebras. We will examine the structure of finite dimensional matrix Lie groups, the exponential and differentiation maps, as well as compact Lie groups. We will also study Lie algebras, ideals and homomorphisms, nilpotent and solvable Lie algebras, Cartan subalgebras, semisimplicity and root systems, and the classification of semisimple Lie algebras. This classification is not only a fundamental result in Lie Theory, but is also an archetype of classifications that appear in other areas of math. More amazingly, this classification is embodied in simple combinatorial pictures called Dynkin diagrams, which underlie surprisingly disparate fields, such as geometric group theory, quiver representation theory, and string theory. Four class meetings per week.

Requisite: MATH 350 or consent of the instructor. Fall semester.

#### 410 Galois Theory

The quadratic formula shows us that the roots of a quadratic polynomial possess a certain symmetry. Galois Theory is the study of the corresponding symmetry for higher degree polynomials. We will develop this theory starting from a basic knowledge of groups, rings, and fields. One of our main goals will be to prove that there is no general version of the quadratic formula for a polynomial of degree five or more. Along the way, we will also show that a circular cake can be divided into 17 (but not 7) equal slices using only a straight-edged knife.

### Statistics

#### 108 Statistical Ethics and Institutions

(Offered as STAT 108 and ECON 108) This course will provide a rigorous presentation of fundamental statistical principles and ethics. We will discuss standards for relationships between statisticians and policymakers, researchers, the press, and other institutions, as well as the standards for interactions between statisticians and their employers/clients, colleagues and research subjects. The course will explore how the interplay of institutions (e.g., organizations, systems, laws, codes of professional ethics) and the broader sociopolitical culture affect the production of reliable, high quality statistics. Students will also explore the implications of statistical principles and ethics for the operation of national, regional, and international official statistical systems. In addition, we will investigate the proper place of official statistics within a government system that operates with separate branches. Students will gain a strong foundation in international statistical principles and professional ethics as well as an understanding and the tools to assess the quality of the statistics they use. The course is designed to make students responsible and effective supporters of reliable, high quality statistics in their professions. Students will particularly learn how to assess the quality of official statistics produced by governments and how to identify areas for improvement. Examples, case studies, readings from statistical practice, and discussion will provide a full appreciation of real world applications. The course is also intended for non-majors interested in an introduction to quantitative social science and the use of data in public policy.

## Mathematics and Statistics

**Mathematics**

*Major Program*. Mathematics majors must complete MATH 111, 121, 211, 271 or 272, 350, and 355. In place of MATH 111, majors may complete MATH 105 and 106. Along with the required courses, a major must complete three elective courses in Mathematics numbered between 135 and 490. At least two of these electives must be numbered 200 or higher. In addition, a major must complete two other courses, each of which is either an elective course in Mathematics numbered between 135 and 490 or a course from outside Mathematics, but in a related field, chosen from among COSC 211, 311, and 401; ECON 300, 301, 361, and 420; any Physics course numbered 116 or higher; any Astronomy course numbered 226 or higher; and any Statistics course numbered 200 or higher. Statistics courses cross-listed with Mathematics count as Mathematics electives. The additional requirement of two courses can be satisfied by taking two math electives, one math elective and one related-fields course, or two related-fields courses. Requests for alternative courses must be approved in writing by the chair of the Department in consultation with the Mathematics faculty within the Department. Honors students may petition the department to count one math thesis course as an elective toward the major.

*Double Majors in Mathematics and Statistics. *Students electing a double major in Mathematics and Statistics may count MATH 111 and MATH 121 towards both majors. A maximum of one additional course taken to complete the Statistics major may be counted towards the Mathematics major.

*Comprehensive Examination*. A comprehensive examination will be given near the beginning of the spring semester of the senior year. (Those who will complete their studies in the fall semester may elect instead to take the comprehensive examination at the beginning of that semester.) The examination covers MATH 211, MATH 271 or 272, and a choice of MATH 350 or 355. More information about the comprehensive examination, including regulations and study materials, can be found on the Department website.

*Honors Program in Mathematics*. Students are admitted to the Honors Program on the basis of a qualifying examination given at the beginning of the spring semester of their junior year and the acceptance of a thesis proposal. (Those for whom the second semester of the junior year occurs in the fall may elect instead to take the qualifying examination at the beginning of that semester.) If a student is accepted to the Honors Program, they will finalize a topic in consultation with Mathematics faculty. After intensive study of this topic, the candidate will write a report in the form of a thesis which should be original in its presentation of material, if not in content. In addition, the candidate will report to the departmental colloquium on their thesis work during the senior year. Honors candidates are also required to complete MATH 345 and at least one Mathematics course numbered 400 to 489.

** **

**Statistics**

*Major Program. *The minimum requirements for the Statistics major include MATH 111 and 121; STAT 111, 135, or 136 (STAT 135 or 136 strongly recommended); STAT 230, 231, 360, 370, and 495; and at least 4 elective courses from among groups A, B, and C below. The combination of elective courses counted towards the Statistics major must be one of the following:

- 3 courses from group A, and 1 course from group B;
- 2 courses from group A, and 2 courses from group B;
- 2 courses from group A, 1 course from group B, and 1 course from group C
- 1 course from group A, 2 courses from group B, and 1 course from group C.

The groups:

- Statistics courses numbered 200 or above (statistical breadth);
- Computer Science courses: COSC 111, COSC 112, COSC 211, COSC 311 (computing requirement);

BIOL/CHEM 250, COSC 254, COSC 257, COSC 355, MATH 271, MATH 272, MATH 355, MATH 365.

*Double majors in Mathematics and Statistics.* Note that for double majors, MATH 111, MATH 121, and at most one other course (usually MATH/STAT 360) can be counted towards both the Mathematics and Statistics majors. Aside from this permitted overlap, statistics, mathematics, or computer science courses counted towards the statistics major may not also be counted towards the mathematics major.

*Comprehensive Evaluation. *All Statistics majors will enroll in the capstone course STAT 495 (Advanced Data Analysis). Beginning with the class of 2021, successful completion of this course satisfies the comprehensive evaluation in Statistics.

*Honors Program in Statistics. *For a degree with Honors, a student must have demonstrated the ability to pursue independent work fruitfully and exhibit a strong motivation to engage in research. To apply to the Honors Program, students must have an average grade of B+ or higher in Statistics 230, 231, 360, and 370. Students are also expected to have completed STAT 370 before the first semester of thesis work is undertaken. E students interested in theses should plan accordingly. Students are admitted to the Honors Program on the basis of a thesis proposal which must be accepted by the department. More information about the Honors Program can be found on the Department website.

## Mathematics and Statistics

**Mathematics**

*Major Program*. Mathematics majors must complete MATH 111, 121, 211, 271 or 272, 350, and 355. In place of MATH 111, majors may complete MATH 105 and 106. Along with the required courses, a major must complete three elective courses in Mathematics numbered between 135 and 490. At least two of these electives must be numbered 200 or higher. In addition, a major must complete two other courses, each of which is either an elective course in Mathematics numbered between 135 and 490 or a course from outside Mathematics, but in a related field, chosen from among COSC 211, 311, and 401; ECON 300, 301, 361, and 420; any Physics course numbered 116 or higher; any Astronomy course numbered 226 or higher; and any Statistics course numbered 200 or higher. Statistics courses cross-listed with Mathematics count as Mathematics electives. The additional requirement of two courses can be satisfied by taking two math electives, one math elective and one related-fields course, or two related-fields courses. Requests for alternative courses must be approved in writing by the chair of the Department in consultation with the Mathematics faculty within the Department. Honors students may petition the department to count one math thesis course as an elective toward the major.

*Double Majors in Mathematics and Statistics. *Students electing a double major in Mathematics and Statistics may count MATH 111 and MATH 121 towards both majors. A maximum of one additional course taken to complete the Statistics major may be counted towards the Mathematics major.

*Comprehensive Examination*. A comprehensive examination will be given near the beginning of the spring semester of the senior year. (Those who will complete their studies in the fall semester may elect instead to take the comprehensive examination at the beginning of that semester.) The examination covers MATH 211, MATH 271 or 272, and a choice of MATH 350 or 355. More information about the comprehensive examination, including regulations and study materials, can be found on the Department website.

*Honors Program in Mathematics*. Students are admitted to the Honors Program on the basis of a qualifying examination given at the beginning of the spring semester of their junior year and the acceptance of a thesis proposal. (Those for whom the second semester of the junior year occurs in the fall may elect instead to take the qualifying examination at the beginning of that semester.)

## Mathematics and Statistics

**Mathematics**

*Major Program*. Mathematics majors must complete MATH 111, 121, 211, 271 or 272, 350, and 355. In place of MATH 111, majors may complete MATH 105 and 106. Along with the required courses, a major must complete three elective courses in Mathematics numbered between 135 and 490. At least two of these electives must be numbered 200 or higher. In addition, a major must complete two other courses, each of which is either an elective course in Mathematics numbered between 135 and 490 or a course from outside Mathematics, but in a related field, chosen from among COSC 211, 311, and 401; ECON 300, 301, 361, and 420; any Physics course numbered 116 or higher; any Astronomy course numbered 226 or higher; and any Statistics course numbered 200 or higher. Statistics courses cross-listed with Mathematics count as Mathematics electives. The additional requirement of two courses can be satisfied by taking two math electives, one math elective and one related-fields course, or two related-fields courses. Requests for alternative courses must be approved in writing by the chair of the Department in consultation with the Mathematics faculty within the Department. Honors students may petition the department to count one math thesis course as an elective toward the major.

*Double Majors in Mathematics and Statistics. *Students electing a double major in Mathematics and Statistics may count MATH 111 and MATH 121 towards both majors. A maximum of one additional course taken to complete the Statistics major may be counted towards the Mathematics major.

*Comprehensive Examination*. A comprehensive examination will be given near the beginning of the spring semester of the senior year. (Those who will complete their studies in the fall semester may elect instead to take the comprehensive examination at the beginning of that semester.) The examination covers MATH 211, MATH 271 or 272, and a choice of MATH 350 or 355. More information about the comprehensive examination, including regulations and study materials, can be found on the Department website.

*Honors Program in Mathematics*. Students are admitted to the Honors Program on the basis of a qualifying examination given at the beginning of the spring semester of their junior year and the acceptance of a thesis proposal. (Those for whom the second semester of the junior year occurs in the fall may elect instead to take the qualifying examination at the beginning of that semester.) If a student is accepted to the Honors Program, they will finalize a topic in consultation with Mathematics faculty. After intensive study of this topic, the candidate will write a report in the form of a thesis which should be original in its presentation of material, if not in content. In addition, the candidate will report to the departmental colloquium on their thesis work during the senior year. Honors candidates are also required to complete MATH 345 and at least one Mathematics course numbered 400 to 489.

** **

**Statistics**

*Major Program. *The minimum requirements for the Statistics major include MATH 111 and 121; STAT 111, 135, or 136 (STAT 135 or 136 strongly recommended); STAT 230, 231, 360, 370, and 495; and at least 4 elective courses from among groups A, B, and C below. The combination of elective courses counted towards the Statistics major must be one of the following:

- 3 courses from group A, and 1 course from group B;
- 2 courses from group A, and 2 courses from group B;
- 2 courses from group A, 1 course from group B, and 1 course from group C
- 1 course from group A, 2 courses from group B, and 1 course from group C.

The groups:

- Statistics courses numbered 200 or above (statistical breadth);
- Computer Science courses: COSC 111, COSC 112, COSC 211, COSC 311 (computing requirement);

BIOL/CHEM 250, COSC 254, COSC 257, COSC 355, MATH 271, MATH 272, MATH 355, MATH 365.

*Double majors in Mathematics and Statistics.* Note that for double majors, MATH 111, MATH 121, and at most one other course (usually MATH/STAT 360) can be counted towards both the Mathematics and Statistics majors. Aside from this permitted overlap, statistics, mathematics, or computer science courses counted towards the statistics major may not also be counted towards the mathematics major.

*Comprehensive Evaluation. *All Statistics majors will enroll in the capstone course STAT 495 (Advanced Data Analysis). Beginning with the class of 2021, successful completion of this course satisfies the comprehensive evaluation in Statistics.

*Honors Program in Statistics. *For a degree with Honors, a student must have demonstrated the ability to pursue independent work fruitfully and exhibit a strong motivation to engage in research. To apply to the Honors Program, students must have an average grade of B+ or higher in Statistics 230, 231, 360, and 370. Students are also expected to have completed STAT 370 before the first semester of thesis work is undertaken. E students interested in theses should plan accordingly. Students are admitted to the Honors Program on the basis of a thesis proposal which must be accepted by the department. More information about the Honors Program can be found on the Department website.

*Honors Program in Mathematics*. Students are admitted to the Honors Program on the basis of a qualifying examination given at the beginning of the spring semester of their junior year and the acceptance of a thesis proposal. (Those for whom the second semester of the junior year occurs in the fall may elect instead to take the qualifying examination at the beginning of that semester.) If a student is accepted to the Honors Program, they will finalize a topic in consultation with Mathematics faculty. After intensive study of this topic, the candidate will write a report in the form of a thesis which should be original in its presentation of material, if not in content. In addition, the candidate will report to the departmental colloquium on their thesis work during the senior year. Honors candidates are also required to complete MATH 345 and at least one Mathematics course numbered 400 to 489.

**Statistics**

*Major Program. *The minimum requirements for the Statistics major include MATH 111 and 121; STAT 111, 135, or 136 (STAT 135 or 136 strongly recommended); STAT 230, 231, 360, 370, and 495; and at least 4 elective courses from among groups A, B, and C below. The combination of elective courses counted towards the Statistics major must be one of the following:

- 3 courses from group A, and 1 course from group B;
- 2 courses from group A, and 2 courses from group B;
- 2 courses from group A, 1 course from group B, and 1 course from group C
- 1 course from group A, 2 courses from group B, and 1 course from group C.

The groups:

- Statistics courses numbered 200 or above (statistical breadth);
- Computer Science courses: COSC 111, COSC 112, COSC 211, COSC 311 (computing requirement);

BIOL/CHEM 250, COSC 254, COSC 257, COSC 355, MATH 271, MATH 272, MATH 355, MATH 365.

*Double majors in Mathematics and Statistics.* Note that for double majors, MATH 111, MATH 121, and at most one other course (usually MATH/STAT 360) can be counted towards both the Mathematics and Statistics majors. Aside from this permitted overlap, statistics, mathematics, or computer science courses counted towards the statistics major may not also be counted towards the mathematics major.

*Comprehensive Evaluation. *All Statistics majors will enroll in the capstone course STAT 495 (Advanced Data Analysis). Beginning with the class of 2021, successful completion of this course satisfies the comprehensive evaluation in Statistics.

*Honors Program in Statistics. *For a degree with Honors, a student must have demonstrated the ability to pursue independent work fruitfully and exhibit a strong motivation to engage in research. To apply to the Honors Program, students must have an average grade of B+ or higher in Statistics 230, 231, 360, and 370. Students are also expected to have completed STAT 370 before the first semester of thesis work is undertaken. E students interested in theses should plan accordingly. Students are admitted to the Honors Program on the basis of a thesis proposal which must be accepted by the department. More information about the Honors Program can be found on the Department website.
