Alexei Oblomkov (UMass Amherst)

In our recent work with Andrei Okounkov, Rahul Pandharipande and Miguel Moreira we proved Virasoro relations for the integrals of the tautological classes over the moduli space of stable pairs on a compact topic three-fold. As an easy consequence of the relations we get previously unknown relations between the integrals of tautological classes on the Hilbert scheme of points on a compact surface. I will start with the case of Hilbert scheme of points on the surface while aiming to explain something about the case of the stable pairs by end of the talk.
