11.4.25 Pedram Hekmati (Auckland)
Correction terms, involutions and Seiberg-Witten theory

Abstract: Correction terms are numerical invariants of 3-manifolds derived from Floer theory. In Seiberg-Witten Floer theory, involutions play a special role, as they can couple to the intrinsic charge conjugation symmetry and yield different flavours of equivariant Floer cohomology. In this talk, I will explain how this leads to three distinct families of correction terms and highlight some of their applications. This is joint work with David Baraglia.
