Title: Open-closed Gromov-Witten invariants of toric Calabi-Yau 3-orbifolds
Abstract: This is a preparatory talk for Zhengyu’s talk last week. I will discuss open Gromov-Witten invariants of toric CY 3-orbifolds, which count stable orbifold maps with certain Lagrangian boundary conditions, and explain how to compute them via localization. I will then specialize to the case of disk invariants and discuss a mirror theorem for disk potentials by Fang-Liu-Tseng.
