Titel:Weighted Cohomology, Hodge Theory and Intersection Cohomology of Shimura Varieties
Abstract:We prove that the intersection cohomology of the Baily-Borel compactification of a complex Shimura variety is identified with the top weight quotient of the mixed Hodge structure on the reductive Borel-Serre compactification. This yields canonical cup products and functorial pullbacks on the intersection cohomology
