Formality of equivariant intersection cohomology

Algebraic Geometry 2007-05-23 v2

Abstract

We present several approaches to equivariant intersection cohomology. We show that for a complete algebraic variety acted by a connected algebraic group GG it is a free module over H(BG)H^*(BG). The result follows from the decomposition theorem or from a weight argument.
