SUMMARY:Scattering Diagrams from Holomorphic Discs in Log Calabi-Yau Surfaces
DESCRIPTION:Algebraic Geometry in String Theory Seminar \nSpeaker: Sam Bardwell-Evans\, Boston University\n\n\nTitle: Scattering Diagrams from Holomorphic Discs in Log Calabi-Yau Surfaces\n\nAbstract: In this talk\, we construct special Lagrangian fibrations for log Calabi-Yau surfaces and scattering diagrams from Lagrangian Floer theory of the fibers. These scattering diagrams recover the algebro-geometric scattering diagrams of Gross-Pandharipande-Siebert and Gross-Hacking-Keel. The argument relies on a holomorphic/tropical disc correspondence to control the behavior of holomorphic discs\, allowing us to relate open Gromov-Witten invariants to log Gromov-Witten invariants. This talk is based on joint work with Man-Wai Mandy Cheung\, Hansol Hong\, and Yu-Shen Lin.
