1、唐鑫星 清华大学丘成桐数学中心:P^1 topological sigma model, Toda hierarchy and W symmetry

摘要:This is a summary report. First I will review the Lax formalism, dressing operators, wave functions, tau function and phase functions around the Toda hierarchy. Next I will talk about the W symmetry of this hierarchy. Furthermore, I will explain the W symmetry in a geometric way.

2、李逸凡 清华大学丘成桐数学中心:Algebraic approaches to LG B-models

摘要:In this talk, I will briefly survey two algebraic approaches to the construction of LG B-model state spaces along with the flat structures and the relation between this two approaches.
