Abstract
Let be a symplectic manifold, and let be a symplectic automorphism. Then, induces an auto-equivalence defined on the Fukaya category of . In this paper, we prove that the categorical entropy of bounds the topological entropy of from below where is a Weinstein manifold and is compactly supported. Moreover, being motivated by the work of Cineli, Ginzburg, and Gurel, we propose a conjecture which generalizes a result in dynamical system.
