# School Whittaker Colloquium by Edward Witten

The School of Mathematics Whittaker Colloquium will be given by Professor Edward Witten (Institute for Advanced Study, Princeton) at 4PM on Friday, 13th May in the Main Lecture Room of the Swann Building on the King's Buildings campus.

"A New Look At Integrable Spin Systems''

Abstract: Integrable models of statistical mechanics in two dimensions, such as the Ising model, have provided important and surprising examples and have been studied from many points of view by both physicists and mathematicians. In recent years, Kevin Costello has developed a new approach to these models, using a four-dimensional cousin of three-dimensional Chern-Simons gauge theory in which the spectral parameter'' has a geometric explanation. This talk will be primarily an introduction to the work of Costello.
