Special Year 2007-08: New Connections of Representation Theory to Algebraic Geometry and Physics - Seminar

Jones-Witten knot invariants and, time permitting, Chern-Simons perturbation theory will be discussed.

This will be a discussion session for Gukov's talk, and/or a lecture on the background material, such as Gaussian integrals of the free theory, formal Feynman expansions etc.

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...

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.

This seminar is intended to cover background material or serve as a discussion session for the seminar "Yang-Mills theory for mathematicians", which will start on the following week. The first talk will give a brief overview of the concepts of...

This seminar will cover such topics as: Jones-Witten knot invariants, large N duality, knot invariants and Gromov-Witten invariants, topological vertex, Nekrasov's partition function and geometric engineering. The first lecture will give an overview...
