Invariance of tautological equations
Y.P. Lee, University of Utah


Finding relations in the tautological rings of the moduli spaces of stable curves has been an important question. In this talk, I will propose a conjectural framework of deriving all/some tautological equations. These conjectures are inspired by a study of Givental's axiomatic Gromov--Witten theory, for which some background will be provided.
