Title:
The Lagrangian cobordism group of Weinstein manifolds
Speaker:
Abstract:
Lagrangian cobordisms induce exact triangles in the Fukaya category. But how many exact triangles can be recovered by Lagrangian cobordisms? One way to measure this is by comparing the Lagrangian cobordism group to the Grothendieck group of the Fukaya category. In this talk, we discuss the setting of exact conical Lagrangian submanifolds in Liouville manifolds and compute Lagrangian cobordism groups of Weinstein manifolds. We conclude that in this setting not always all exact triangles come from Lagrangian cobordisms.
