CONGRATULATIONS to Professor Abouzaid!

Selection of the 2018 Fellows of the American Mathematical Society

Sixty three Mathematical scientists from around the world have been named Fellows of the American Mathematical Society (AMS) for 2018, the program’s sixth year and on November 1, 2017 Professor Mohammed Abouzaid was selected as one of the new AMS Fellows for 2018.

The Fellows of the AMS designation recognizes members who have made outstanding contributions to the creation, exposition, advancement, communication, and utilization of mathematics. Among the goals of the program are to create an enlarged class of mathematicians recognized by their peers as distinguished because of their contributions to the profession, and to honor excellence.

Regarding the new Fellows of the AMS program and the Society, AMS President Kenneth A. Ribet says,”This year’s class of AMS Fellows has been selected from a large and deep pool of superb candidates. It is my pleasure and honor as AMS President to congratulate the new Fellows for their diverse contributions to the mathematical sciences and to the mathematics profession.”

A description of the Fellows program is at http://www.ams.org/profession/ams-fellows.

Founded in 1888 to further mathematical research and scholarship, the American Mathematical Society fulfills its mission through programs and services that promote mathematical research and its uses, strengthen mathematical education, and foster awareness and appreciation of mathematics and its connections to other disciplines and to everyday life.

Fall 2017 Joseph Fels Ritt Lectures

Come join us Monday October 30th & Wednesday November 1st at 4:30 pm in RM 520, Professor László Székelyhidi Jr. (University of Leipzig) will be giving a special lecture about “The h-principle in fluid dynamics”.

Professor László Székelyhidi Jr. (University of Leipzig)

Title

The h-principle in Fluid Dynamics

Abstract

It is known since the pioneering work of V. Scheffer and A. Shnirelman in the 1990s that weak solutions of the incompressible Euler equations behave in very unexpected ways. Such solutions are highly non-unique and have several unphysical features such as arbitrary growth of energy. Nevertheless, weak solutions in three space dimensions have been studied in connection with a conjecture of L. Onsager from 1949 concerning anomalous dissipation and, more generally, because of their possible relevance to Kolmogorovs K41 theory of turbulence.

In a series of joint publications with Camillo De Lellis we established a connection between the theory of weak solutions of the Euler equations and the Nash-Kuiper theorem on rough isometric immersions. Through this connection one can interpret the wild behavior of weak solutions of the Euler equations as an instance of Gromov’s celebrated h-principle. In these lectures I will explain this connection, outline the most recent progress concerning Onsager’s conjecture and discuss some future directions.

Invidious Comparisons: International politics, the Fields Medal, and the past, present, and future of mathematics, 1936-1966

Title

Invidious Comparisons: International Politics, the Fields Medal, and the Past, Present, and Future of Mathematics, 1936-1966 

Abstract 

First presented in 1936, the Fields Medal quickly became one of mathematicians’ most prestigious, famous, and in some cases notorious prizes. Because its deliberations are confidential, we know very little about the early Fields Medals: how winners were selected, who else was considered, what values and priorities were debated—all these have remained locked in hidden correspondence. Until now. This talk will analyze newly discovered letters from the 1950 and 1958 Fields Medal committees, which Dr. Barany claims demands a significant change to our understanding of the first three decades of medals. He will show, in particular, that the award was not considered a prize for the very best mathematicians, or even for the very best young mathematicians. Debates from those years also shed new light on how the age limit of 40 came about, and what consequences this had for the Medal and for the mathematics profession. ​This talk will argue that 1966 was the turning point that set the course for the Fields Medal’s more recent meaning.

This event is free and open to the public.
This event is part of the New York History of Science Lecture Series.

Fall 2017 Samuel Eilenberg Lecture Series

Come join us every Thursday (Fall term) at 2:40 pm in RM 520, Professor Paul Seidel (MIT) will be giving a series of lectures about “Automorphisms and Fibrations in Symplectic and Noncommutative Geometry.”

TITLE
“Automorphisms and fibrations in symplectic and noncommutative geometry”

ABSTRACT
“In algebraic geometry, there are special theories for a space equipped with a function, or with a vector field, or a group action. Such geometric features allow one both to analyze the given space, and to introduce new objects and structures on it. Motivated by mirror symmetry, we will try to reconsider such features from the more general viewpoint of noncommutative geometry. For instance, given an algebra A, thought of as corresponding to a noncommutative space, what is a function on A? What are the level sets of that function?

Symplectic geometry provides a rich source of situations where the answer to those questions is important, and makes a difference in concrete topological applications.”
