Distinguishing fillings via dynamics of Fukaya categories

Given a Weinstein domain M and a compactly supported, exact symplectomorphism ϕ, one can construct the open symplectic mapping torus Tϕ. Its contact boundary is independent of ϕ and thus Tϕ gives a Weinstein filling of T0×M, where T0 is the punctured 2-torus. In this talk, we will outline a method to distinguish Tϕ from T0×M using dynamics and deformation theory of their wrapped Fukaya categories. This will involve the intermediate step of constructing a mirror symmetry inspired algebro-geometric model related to Tate curve for the wrapped Fukaya category of Tϕ and exploiting the dynamics of these models to distinguish them.
