Place: MCM410

Abstract: I will report on joint work in progress with A. Hirschi on the construction of a homotopy involutive bi-Lie algebra structure on the reduced negative equivariant free loop space of a smooth manifold. The construction is based on Irie's de Rham chains. As an application, I will describe how to carry out a geometric version of a proposal by Cieliebak–Fukaya–Latschev for defining a higher genus open Gromov–Witten invariant valued in this homotopy involutive bi-Lie algebra.
