Abstract:
We study intersection cohomology of moduli spaces of semist
able vector bundles
on a complex algebraic surface. Our main result relates inte
rsection Poincar ́e polynomials of
the moduli spaces to Donaldson-Thomas invariants of the sur
face. In support of this result, we
compute explicitly intersection Poincar ́e polynomials fo
r sheaves with rank two and three on
ruled surfaces.
