### Hypercommutative algebras, Batalin-Vilkovisky algebras, and Givental group I

Shadrin, S *(Universiteit van Amsterdam)*

Seminar Room 1, Newton Institute

#### Abstract

I'll make a survey of several different ways to define a so-called Givental group. This group is, in some interpretations, a group of symmetries of the representations of the operad Hycomm, and plays an important role in the correspondence between the operads Hycomm and BV. I'll also try to make a link of this formalism to the topological recursion arising in the matrix models theory.
