Cohomology of the moduli space of curves
Abstract: The moduil space of curves carries tautological
cohomology classes. I will discuss the study of
relations amongst these classes starting with ideas
of Mumford in 1980s. The subject advanced in the
1990s with conjectures of Faber and Faber-Zagier.
I will explain the current state of affairs based
on Pixton's conjectures related to
cohomological field theories. The talk represents
joint work with A. Pixton and D. Zvonkine.
