Title：A infinity multi-modules from quilts and applications

Time&Venue：2025年10月29日（星期三）14:00 - 15:00 & 晨兴 110

Abstract：Invariants defined by counting pseudo-holomorphic maps from Riemann surfaces with boundary are uniquitous in symplectic geometry, low dimensional topology and mathematical physics. Some examples include various types of Floer homologies, Fukaya categories and Gromov-Witten theory. In this talk I will give a short survey about a generalization of this developed by Wehrheim-Woodward called pseudo-holomorphic quilts. Then I will present some applications of quilted invariants including a proof of a conjecture of Seidel regarding the Floer homology of composed Dehn twists.
