摘要
In this talk, we explain a proof that the fixed-point Floer cohomology of the global monodromy of a Lefschetz fibration, whose total space is a Weinstein manifold, is isomorphic to the Hochschild cohomology with coefficients in the global monodromy bimodule.
Moreover, this isomorphism is given by the closed-open string map with a twisting. This concludes, partially, a question posed by Paul Seidel. Previously, Bai-Seidel showed that the twisted closed-open string map is injective.
This is an ongoing joint work with Y Gao, L Han and S Zhang.
