One can construct \textbf{the open symplectic mapping torus} $T_\phi$ for a given Weinstein manifold $M$ and a compactly supported exact symplectomorphism $\phi$. $T_\phi$ is another Weinstein manifold, and its contact boundary is independent of $\phi$. In this talk, we will show how to distinguish $T_\phi$ from $T_{1_M}$. We first construct an algebraic model- \textbf{the mapping torus category}- for the (wrapped) Fukaya category of $T_\phi$. The construction is inspired by mirror symmetry for the punctured torus, and it involves the geometry of the Tate curve. Then we will exploit dynamics and deformation theory of these algebraic models to show they are not equivalent categories.

This talk is part of the Algebraic Geometry Seminar series.
