Place: Room 614, Science & Education Building, U. Haifa
Speaker: Sergei Merkulov (University of Luxembourg)
Title: Gravity and moduli spaces M_g,n
Using Thomas Willwacher’s twisting endofunctor, and Kevin Costello’s theory of partially compactified moduli spaces of algebraic curves of the arbitrary genus with marked points, we introduce a new dg properad which contains Ezra Getzler’s gravity operad controlling genus zero moduli spaces, and, surprisingly, the properad of V. Drinfeld’s quasi Lie bialgebras. We discuss its applications in the theory of moduli spaces M_g,n.
