Virasoro constraints for PT theory

Algebraic Geometry

Speaker: Alexei Oblomkov, UMass Amherst
Location: 2112 Msb
Start time: Wed, Feb 28 2018, 11:00AM

Talk is based on the joint work with Okounkov and Pandharipande. I state an explicit formula for the Gromov-Witten/Donaldson-Thomas correspondence with descendants. I will explain an idea of a proof of the formula for toric varieties. The correspondence allows us to prove Virasoro constraints for Donaldson-Thomas theory.
