The tautological ring of $M_g$

Tuesday, November 30, 2010 -
4:30pm to 6:30pm
I will talk about an approach to the ring generated by the kappa classes via the moduli space of stable quotients. The main new result (with A. Pixton) is a proof of a conjecture by Faber and Zagier of an elegant set of relations. Whether these are all the relations is an interesting question. I will discuss the data on both sides.
