Title: homotopy of A_{n,k} algebra

Abstract: In this talk, we will use the Kuranishi structure of moduli space of stable discs to define the A_{n,k} algebra. Then the homotopy between a sequence of A_{n,k} algebras with increasing index n,k will be used to get an A_\infty algebra. These homotopies can be obtained from a A_{n,k} version of corresponding theorem in chapter 4.

Venue: Room 09 at Quan-Zhai (全斋), Beijing International Center for Mathematical Research, Peking University.
