Workshop on the Bezrukavnikov equivalence

The Workshop is a joint activity of the Arithmetic Geometry research groups in Bonn, Essen and Münster and will take place at three Fridays in the coming term. The aim of the workshop is to understand the work of Roman Bezrukavnikov about an equivalence between certain constructible sheaves on an affine flag variety and certain coherent sheaves on a variety related to the Springer resolution of the nilpotent cone. It gives a categorification of work of Kazhdan and Lusztig on the realization of an affine Hecke algebra as the equivariant K-theory of an algebraic variety.
