Speaker: Vladimir Rubtsov

Title: 2-valued algebraic groups, the Chazy equation, and quasimodular forms

Abstract:
I will discuss some (un)known relations between the objects in the title.

In particular, the celebrated Chazy equation emerges as an associativity condition. 

The talk is based on ongoing joint work with V. Buchstaber and M. Kornev (Steklov Mathematical Institute, RAS).
