Welcome to this seminar held by Noah Porcelli (Imperial College London) with title "Framed bordism of exact Lagrangians via Floer homotopy".
Abstract: Lagrangian Floer theory is a useful tool for studying the structure of the homology of Lagrangian submanifolds. In some cases, it can be used to detect more- we show it can detect the framed bordism class of certain Lagrangians and in particular recover a result of Abouzaid--Alvarez-Gavela--Courte--Kragh about smooth structures on exact Lagrangians in cotangent bundles of spheres. The main technical tool we use is Large's recent construction of a stable-homotopical enrichment of Lagrangian Floer theory.
This is based on joint work-in-progress with Ivan Smith.
