报告摘要：The open Gromov-Witten invariants of smooth toric Calabi-Yau threefolds in mathematics, as well as the A-model topological string amplitudes in physics, can be computed by the method of topological vertex . In this talk, I will introduce our recent work on the three component KP integrability of the topological vertex, which proves the Aganagic-Dijkgraaf-Klemm-Marino-Vafa Conjecture proposed in 2006. As a corollary, all open Gromov-Witten theory of smooth toric Calabi-Yau threefolds are related to multi-component KP hierarchy. This talk is based on a joint work with Zhiyuan Wang and Jian Zhou.
