Local Intersection Cohomology of Baily–Borel Compactifications
Published online by Cambridge University Press: 04 December 2007
Abstract
The local intersection cohomology of a point in the Baily–Borel compactification (of a Hermitian locally symmetric space) is shown to be canonically isomorphic to the weighted cohomology of a certain linear locally symmetric space (an arithmetic quotient of the associated self-adjoint homogeneous cone). Explicit computations are given for the symplectic group in four variables.
