Title: Counting disks in toric varieties

Date: Mon, Jun 24, 2013, 13:15 - 14:45

Place: Seminar Room A

Abstract: For a toric manifold X and a Lagrangian torus fiber L in X,
Fukaya-Oh-Ohta-Ono defined open Gromov-Witten invariants which are
virtual enumerations of holomorphic disks in X with boundary
conditions in L. Qualitative and quantitative properties of these open
Gromov-Witten invariants play important roles in the symplectic
geometry and mirror symmetry of X. Open Gromov-Witten invariants are
difficult to compute because standard methods in Gromov-Witten theory
(such as virtual localization) are not applicable. In this talk we
explain a geometric method that leads to a complete calculation of
these open Gromov-Witten invariants for compact semi-Fano toric
manifolds. This is joint work with K. Chan, S.-C. Lau, N. C. Leung.
