Seminar on Algebra, Geometry and Physics Okounkov and Pandharipande derived Virasoro constraints for Gromov-Witten theory of P

1. Later and independently, using Teleman reconstruction theorem and its correspondence with topological recursion, Dunin-Barkowski et al. proved that the stationary sector is encoded in the meromorphic forms w_{g,n} computed by the topological recursion for the spectral curve x(z) = z + 1/z, y(z) = \ln z. This statement is equivalent to local Virasoro constraints. I will explain how the non-stationary sector is encoded in same meromorphic forms w_{g,n} and how local Virasoro constraints imply (in a perhaps interesting way) the Virasoro constraints of Okounkov and Pandharipande.This is based on a joint work with Paul Norbury.
