Beibei Liu - Floer lasagna for 2-handlebodies
October 26, 2026
Abstract
Skein lasagna modules are defined for 4-manifold with a link in its boundary by Morrison, Walker and Wedrich using Khovanov homology, and it turns out to be quite effective in detecting exotic structures on 4-manifolds. In this talk, we will discuss about the analogue construction of Floer Lasagnas for 4-manifold using link Floer homology based on Chen. In particular, we will derive the computation for surgeries on unknots and more generally, the family of L-space links. This is joint work with Alishahi and Gorsky.
