Intersection Cohomology of reductive varieties

Algebraic Geometry 2007-05-23 v1 Combinatorics

Abstract

We extend the methods developed in our earlier work to algorithmically compute the intersection cohomology Betti numbers of reductive varieties. These form a class of highly symmetric varieties that includes equivariant compactifications of reductive groups. Thereby, we extend a well-known algorithm for toric varieties.
