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.
