Xavier Blot: The DR-DZ equivalence II

Abstract: This talk is the second of a series of three talks about the DR-DZ equivalence. In the first talk, we explained how the equality of the so-called A-class and B-class in the cohomology of the moduli space of curves implies the equivalence of the DR and DZ hierarchies. In this talk, we explain how to prove the relation A=B using a virtual localization formula.
