题目：Mixed Spin Fields on the Quintic
报告人：李卫平（香港科技大学）
摘要：The Gromov-Witten invariants of the quintic is one of the most famous research topics from the very first day of mirror symmetry to today. There is another physical theory for the quintic polynomial, called Landau-Ginzburg theory. Physicists conjectured that these two theories can be identified via some mysterious transformations. The analytical construction of enumerative invariants in the affine LG-space was given by Fan, Jarvis and Ruan (FJRW invariants). Mixed spin field theory is a mathematical attempt to unlock the mysterious link between GW-invariants and FJRW-invariants. It uses the newly developed technologies such as the cosection localization by Kiem and J.Li and the P-fields theory of Chang and J. Li. It is an on-going joint work with H.L. Chang, J. Li and Melissa Liu.
