Colloquium: Virtual Signed Euler characteristic and application to Vafa-Witten invariants

Colloquium| Institute of Mathematical Sciences

Time14:30-15:30, July 18, Thursday

LocationRoom S407, IMS


Speaker: Yunfeng Jiang, University of Kansas 

Abstract: In joint work with R. Thomas we defined four type of counting invariants for an existing perfect obstruction theory.These invariants have applications to the recently developed Vafa-Witten theory inspired by the S-duality conjecture.In this talk I will talk about the four invariants and their potential applications to the Vafa-Witten theory.
