Lefschetz fibrations on cotangent bundles and some plumbings

Sangjin Lee

We introduce an idea of constructing Lefschetz fibrations of Weinstein manifolds from Weinstein handle decompositions on them. We prove theorems that formulate the idea for the cas…

A comparison of categorical and topological entropies on Weinstein manifolds

Hanwool Bae, Sangjin Lee

Let $W$ be a symplectic manifold, and let $I ¨ : W \to W$ be a symplectic automorphism. Then, $I ¨ $ induces an auto-equivalence $I^¦$ defined on the Fukaya category of $W$ . In this pape…
