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

Presented by: 
S Shadrin Universiteit van Amsterdam
Date: 
Thursday 7th February 2013 - 14:00 to 15:00
Venue: 
INI Seminar Room 1
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.
