Computing cup products in integral cohomology of Hilbert schemes of points on K3 surfaces
Computing cup products in integral cohomology of Hilbert schemes of points on K3 surfaces
We study cup products in the integral cohomology of the Hilbert scheme of $n$ points on a K3 surface and present a computer program for this purpose. In particular, we deal with the question of which classes can be represented by products of lower degrees. Supplementary materials are available with …
