Title	Tautological relations and cohomological field theories
Abstract	Tautological classes form a subring of the Chow ring of the moduli space of curves. There is an explicit set of generators but the set of relations remains unknown. In 2012 Aaron Pixton gave an explicit set of conjectural relations and gave a lot of evidence that these are actually all the relations. I want to compare two proofs of the fact that the conjectural relations are actual relations.
