Abstract Let W be a symplectic manifold, and let $\phi :W \to W$ be a symplectic automorphism. This automorphism induces an auto-equivalence $\Phi $ defined on the Fukaya category of W. In this paper, we prove that the categorical entropy of $\Phi $ provides a lower bound for the topological entropy of $\phi $ , where W is a Weinstein manifold and $\phi $ is compactly supported. Furthermore, motivated by [cCGG24], we propose a conjecture that generalizes the result of [New88, Prz80, Yom87].
