Dongning Wang Seidel elements and mirror transformations

Abstract:

I will talk about the following paper by Eduardo Gonzalez, Hiroshi Iritani:

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.
