Yang-Mills Fields in Super-Critical Dimensions

Speaker: Tristan Riviere, ETH Zurich

Location: Warren Weaver Hall 1302

Date: Monday, December 3, 2012, 3:45 p.m.

Synopsis:

In the early 2000 a series of geometric works, by Donaldson-Thomas and Tian in particular, have stimulated the analysis of Yang-Mills fields in dimension larger than the conformal one. We shall recall the main ingredients, developed mostly in the 80's, for the study of Yang-Mills Fields in critical and sub-critical dimensions. We will explain why most of these ingredients are inoperative in higher dimensions. The purpose of this talk is to present a new alternative framework for the calculus of variations of Yang-Mills Lagrangian in super-critical dimensions.
