Time: Monday Oct. 22, 7--9 pm

Speaker: Feng Wang (Peking University)

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

Abstract: We will define some deformations of the A_infty algebra associated with Lagrangian submanifold. Under some conditions of cohomolgical groups, we can find suitable element to deform the A_infty structure. This will give us the definition of Floer homology. And we will also talk about the Bott-Morse case which deals with the non-transversal intersection of the two Lagrangian submanifolds.
