A new cohomology class in the moduli space of stable curves

Paul Norbury (Melbourne)

Thursday 11 May 12:00–13:00 in Carslaw 535A.

Please join us for lunch after the talk!

Abstract: We will define a cohomology class in the moduli space of stable curves with many beautiful properties analogous to properties of intersection numbers on the moduli space proven in the Witten-Kontsevich theorem. Applications of this new cohomology class to various enumerative problems will be given.
