Geometry and Topology Seminar
Seiberg-Witten Floer KO-theory and intersection forms of spin 4-manifolds
Jianfen Lin, Professor of Mathematics, Mathematics, UCLA
In this talk, I will explain how to apply Pin(2)-equivariant Seiberg-Witten KO-theory on the Seiberg-Witten Floer spectrum to obtain new 3-manifold invariant and get new constrains on the intersection form of a spin 4-manifolds (closed or with boundary).
