Location: Cramér room
Participating: Dan Petersen (SU)
Abstract:
Andrea Bianchi recently gave a new proof of Mumford's conjecture on the stable rational cohomology of the moduli space of curves (first proven by Madsen and Weiss). I will explain a streamlined and significantly simplified version of Bianchi's argument. (Joint with Ronno Das)
