Weekly seminar: Hiroshi Iritani
Abstract:
Seidel representation associates to a Hamiltonian circle action on a symplectic manifold an invertible element in the quantum cohomology. This can be lifted to the action on quantum D-module and is called "shift operators". In this talk, I will explain how mirrors of toric varieties can be constructed via Seidel representation and shift operators tautologically in Gromov-Witten theory.
