Título: Noncommutative analogues of cohomological field theorie
Resumen: Algebraic structures that are usually referred to as cohomological field theories reflect very rich geometry of Deligne--Mumford compactifications of moduli spaces of curves with marked points. I shall talk about some new rather remarkable algebraic varieties that have a lot in common with [genus 0] Deligne--Mumford spaces, about their topological properties, and about several new algebraic structures that naturally arise from studying those varieties. This is joint work with Sergey Shadrin and Bruno Vallette
