Title: Wall-crossing in Floer theory

Speaker: 홍한솔(연세대학교)

 

Abstract:

The wall-crossing phenomenon in Lagrangian Floer theory refers to a drastic change in holomorphic disk counting while the bounding Lagrangians vary continuously. In particular, wall-crossings for Lagrangian tori can be formulated in terms of cluster transformations, which brings cluster varieties as principal objects into the study of mirror symmetry. I will discuss various features of the wall-crossing in Floer theory, making use of concrete examples, and explain its combinatorial nature.
