Injectivity of a certain cycle map for finite dimensional W-algebras

Representation Theory 2011-12-08 v3 Algebraic Geometry

Abstract

We study a certain cycle map defined on finite dimensional modules for the W-algebra with regular integral central character. Via comparison with the theory in postive characteristic, we show that this map injects into the top Borel-Moore homology group of a Springer fibre. This is the first result in a larger program to completely desribe the finite dimensional modules for the W algebras.
