I will briefly review the definition of Seidel representation, then introduce parametrized group action, Kuranishi structure, equivariant Kuranishi structure and parametrized equivariant Kuranishi structure, and use these to prove the triviality axiom of Seidel representation. To prove the composition axiom, I will construct a Lefschetz fibration, then consider then moduli spaces this space and their Kuranishi structures. Finally, if time permitted, I will mention the extra ingredients needed for orbifold Seidel representation.

Dongning Wang "Proof of the Triviality Axiom and Composition Axiom of Seidel Representation"

Abstract:

I will briefly review the definition of Seidel representation, then introduce parametrized group action, Kuranishi structure, equivariant Kuranishi structure and parametrized equivariant Kuranishi structure, and use these to prove the triviality axiom of Seidel representation. To prove the composition axiom, I will construct a Lefschetz fibration, then consider then moduli spaces this space and their Kuranishi structures. Finally, if time permitted, I will mention the extra ingredients needed for orbifold Seidel representation.

Erkao Bao "On the Fukaya categories of higher genus surfaces"

I will present Abouzaid's paper: http://arxiv.org/abs/math/0606598. He proved that the Grothendieck group of the derived Fukaya category is isomorphic to [math]$H^1(\Sigma)$[/math]
