An overview will be continued by a discussion of basic notions of quantum field theory (path integral, Feynman diagrams etc.)

The goal of the seminar is to cover the formalism of chiral algebras and related constructions that will be used in later talks in geometric Langlands seminar. In this talk an overview of representation theory of affine Lie algebras will be given...

We shall discuss joint work with I Z Ruzsa in which it is shown that if A is a subset of {1,..,N} such that its difference set contains no number of the form $p-1$ for $p$ a prime, then $|A|=O(N\exp(-c\sqrt{4}{\log N}))$ for some absolute $c>0$.

The sign-rank of a real matrix M is the least rank of a matrix R in which every entry has the same sign as the Corresponding entry of M. We determine the sign-rank of every matrix of the form M=[ D(|x AND y|) ]_{x,y}, where D:{0,1,...,n}->{-1,+1} is...

I will give an overview of what is going to be discussed in the seminar during the semester, and start an introduction to the theory. No previous familiarity with geometric Langlands will be assumed.
