Intersection cohomology of reductive varieties

چکیده
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.

Intersection Cohomology Methods in Representation Theory*
In recent years, the theory of group representations has greatly benefited from a new approach provided by the topology of singular spaces, namely intersection cohomology (IC ) theory. Let G be a connected reductive algebraic group over an algebraically closed field (which will be assumed to be C unless otherwise specified) ; although G itself is clearly a non-singular variety, the study of the...
متن کاملWeights in the cohomology of toric varieties
We describe the weight filtration in the cohomology of toric varieties. We present the role of the Frobenius automorphism in an elementary way. We prove that equivariant intersection homology of an arbitrary toric variety is pure. We also obtain a results concerning Koszul duality: nonequivariant intersection cohomology is equal to the cohomology of the Koszul complex IH∗ T (X)⊗ H ∗(T ).
متن کاملVanishing of Odd Dimensional Intersection Cohomology Ii
For a variety where a connected linear algebraic group acts with only finitely many orbits, each of which admits an attractive slice, we show that the stratification by orbits is perfect for equivariant intersection cohomology with respect to any equivariant local system. This applies to provide a relationship between the vanishing of the odd dimensional intersection cohomology sheaves and of t...
متن کاملIntersection cohomology invariants of complex algebraic varieties
In this note we use the deep BBDG decomposition theorem in order to give a new proof of the so-called “stratified multiplicative property” for certain intersection cohomology invariants of complex algebraic varieties.
