Andreas Georgiou '83, Visiting Lecturer in Economics, Amherst College

Lessons for official statistics production around the world from the experience of Greece

Abstract: The seminar will address what lessons can be gleaned from the experience with official statistics production in Greece, both in the period up to the onset of the debt crisis and since then. The seminar will discuss lessons about the appropriate institutional setting, legal framework, statistical culture and statistical practices.

Background on speaker: For 21 years, Andreas Georgiou worked as an economist at the International Monetary Fund in Washington, of which the last 6 years in its Statistics Department. When the Greek debt crisis hit and Greece began teetering toward bankruptcy, he applied online to run the National Statistical Office which had recently become an independent authority and renamed as Hellenic Statistical Authority (ELSTAT). The main task was to rebuild ELSTAT and clean up Greece’s official statistics that had been persistently misreported for years and contributed to the Greek and broader European debt crisis. He got the job, and in August 2010 he moved to Greece for a five-year term as president of ELSTAT. His revision of the country’s public finance statistics according to EU statistical legislation in force revealed the true magnitude of Greece's fiscal problems and formed the basis for EU and international financial assistance to Greece in the years from 2011 till today. However, in the process, Georgiou became a scapegoat for the economic difficulties of the Greek debt crisis by big parts of the Greek political system. He is subjected to multiple prosecutions within Greece for this statistical work, although the statistics produced by ELSTAT under his watch have been consistently validated since 2010 by the statistical office of the EU (Eurostat) and are used in the past seven years for all official business of the government in Greece.

Mathematics Professor Michael Ching named Lazerowitz Lecturer (April 14, 2016)

Congratulations to Michael Ching, who has been named as the 2015-2016 Lazerowitz Lecturer.  His talk, entitled "Shape" took place on Thursday, April 14th in Paino Lecture Hall (Beneski).  The abstract states that the universe around us is full of fascinating shapes: we see them in the natural world, we put them in our buildings, we see them in the remnants of exploded stars. Einstein proposed that the universe itself has an interesting shape - that space is curved. In the world of our imagination, there are even more fantastic shapes that have beautiful and interesting properties: worlds that you can walk all the way around and come back as a mirror image of yourself, surfaces that can be knotted like higher-dimensional pieces of string.

In this talk he will describe how mathematicians think of shapes and understand their fundamental properties. How can we tell two shapes apart? What ways can two different shapes be similar? How can we “measure” shape? Can we hope to build a catalog of all possible shapes?

This ethereal topic has recently started to have more down-to-earth applications. The emergence of “big data” has led to a need for new ways to analyze that data, and one such analysis is to look for interesting shapes therein. Where before we might be happy to find that a set of data forms a straight line, now there are ways to detect circles, surfaces and higher-dimensional shapes hidden in the numbers. These higher-order patterns can illuminate unexpected relationships and tell you something that traditional data analysis might miss.

Cox, Little, and O'Shea to Receive 2016 AMS Steele Prize for Exposition

The AMS Leroy P. Steele Prize for Exposition was awarded to three mathematicians: David Cox (Amherst College), John Little (College of the Holy Cross), and Donal O'Shea (New College of Florida) "for their book Ideals, Varieties, and Algorithms, which has made algebraic geometry and computational commutative algebra accessible not just to mathematicians but to students and researchers in many fields."

Algebraic geometry has a reputation for being impenetrably technical and abstract. By requiring only linear algebra as a prerequisite, the book by Cox, Little, and O'Shea invites a broad audience of readers into this central branch of mathematics. Using geometry to introduce core topics and appealing to computational theory to prove fundamental results, they complement the development of theoretical results with applications to such topics as automated theorem proving and robotics. All of this is delivered with crystal-clear exposition and top-quality writing.

"Even more impressive than [the book's] clarity of exposition is the impact it has had on mathematics," the prize citation states. "CLO, as it is fondly known, has not only introduced many to algebraic geometry, it has actually broadened how the subject could be taught and who could use it." The book helped bring the topic of computational algebra into the mathematical mainstream. In particular, the book's presentation of the theory of Gröbner bases "has done more than any other book to popularize this topic." Gröbner bases provide a way to efficiently automate certain calculations in algebraic geometry. The subject of Gröbner bases has boomed in recent years, in part because of significant applications to such diverse problems as oil exploration, software design, genetics, and robot kinematics.

Originally published by Springer Verlag in 1992, the fourth edition of CLO appeared just this year. The book has truly become a classic. It not only has provided many of today's mathematicians with their first grounding in algebraic geometry, but also has brought this area of mathematics to the service of scientists and engineers. All three authors are top-flight mathematicians at small colleges; O'Shea was at Mount Holyoke College for more than 30 years before becoming the president of New College of Florida in 2012. Their book shows how small colleges make signal contributions to the advancement of mathematics, the training of future mathematicians, and the applications of mathematics to other disciplines. The AMS Steele Prize is one of the highest distinctions in mathematics. 

Cox received the Lester R. Ford Prize from the Mathematical Association of America (2012) and was elected as a Fellow of AMS (2013). Little has received distinctions for his outstanding service to the College of the Holy Cross, including its Distinguished Teaching Award (2003) and the Anthony and Renee Marlon Professorship in the Sciences (2012-2015). In 2008, O'Shea received the Peano Prize for his book The Poincaré Conjecture: In Search of the Shape of the Universe (Walker & Company, 2006).
