Title: A localisation formula in symplectic GW theory
Abstract: I will describe the construction of a global Kuranishi chart for moduli spaces of stable pseudoholomorphic maps and how the construction can be adapted to the equivariant setting whenever the target symplectic manifold carries a Hamiltonian action. Subsequently, I will explain how this leads to a combinatorial formula for the equivariant Gromov-Witten invariants of a Hamiltonian torus manifold satisfying some mild assumptions. This is partially joint work with Mohan Swaminathan.
