The mod 2 index and Seiberg-Witten invariants of spin structures
Location
In this talk I will explain a surprising relation between mod 2 index theory and Seiberg-Witten invariants. This relation arose from my calculation of the mod 2 Seiberg-Witten invariants of spin structures. I will also discuss the proof of this calculation, which uses ideas from families Seiberg-Witten theory and localisation in equivariant cohomology.
