Analysis Seminar

A Hardy Field Extension of Szemeredi's Theorem
Nikos Frantzikinakis
2:00pm|S-101

In 1975 Szemeredi proved that every subset of the integers with positive density contains arbitrarily long arithmetic progressions. Bergelson and Leibman showed in 1996 that the common difference of the arithmetic progression can be a square, a cube...

Towards 2-Dimensional Geometric Langlands Correspondence

H^3 and Gerbal Extensions
Xinwen Zhu
2:00pm|S-101

It is long expected that to study the representation theory of the double loop group and the corresponding Lie algebra, the third cohomology group should play an important role. The idea is that the third cohomology classes are naturally realized...

Special Seminar

An Introduction to the Statistical Mechanics of Random Band Matrices (continued)
Tom Spencer
4:00pm|S-101

Spectral properties of random band matrices can be expressed in terms certain statistical mechanics models. Some of these models are generalizations of the Ising model except that the spins belong the the Poincare superdisc and there is...
