Definition of psi-classes in graph calculus
There is a model of genus expansion of solutions to the WDVV equation based on graph calculus in dGBV algebras. In my talk, I am going to compare it with Gromov-Witten theory. In particular, I'll discuss a definition of psi-classes in terms of graphs. The talk is based on my joint papers with A. Losev and I. Shneiberg.
