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...

Nearly Diagonally Dominant Matrices and Their Applications
10:30am|S-101

I will describe a lower bound for the rank of any real matrix in which all diagonal entries are significantly larger in absolute value than all other entries. This simple result has a surprising number of applications in Geometry, Coding Theory...
