Regards, Dionne, Dan, Joan, and Tillus *** Wednesday, 1 May 2024 Ian Sullivan (UC Davis) Title: Kirby Belts and the Skein Lasagna Module of S2xS2 Abstract: The skein lasagna module of a chosen link homology theory is a new kind of smooth 4-manifold invariant capable of detecting exotic phenomena. In this talk, we define and investigate a certain homotopy colimit of a directed system of tangle complexes whose homology is the skein lasagna module for $\mathfrak{gl}_{2}$ Khovanov-Rozansky homology of S^2\times B^2 with geometrically essential links in the boundary. We then use this new computational technique to compute the skein lasagna module of S^2\times S^2, and to show that the skein lasagna module of S^2\times B^2 recovers Khovanov homology for links in S^1\times S^2.
