The cup product of the Hilbert scheme for K3 surfaces

Manfred Lehn, Christoph Sorger

Published 2000-12-18Version 1

To any graded Frobenius algebra A we associate a sequence of graded Frobenius algebras A^[n] in such a way that for any smooth projective surface X with trivial canonical divisor there is a canonical isomorphism of rings between (H*X)^[n] and the cohomology H*(X^[n]) of the n-th Hilbert scheme of X.
