Tautological relations of Faber-Zagier type
Abstract: The tautological ring of the moduli space of smooth curves of genus g is the subring of its Chow ring generated by the kappa classes. The Faber-Zagier relations are an explicit algebraic description of a large number of relations in this ring, possibly giving all the relations. I will discuss two families of tautological relations defined in a similar fashion to the Faber-Zagier relations.
