Title:Dehn twist and monodromy in symplectic geometry
Abstract:Seidel in his paper [1] shows that the monodromy around a critical point of a Lefschetz fibration of an exact symplectic manifold is isotopic to the Dhen twist along a Lagrangian sphere. We follow his approach [2] to study the Dehn twist operation on Lagrangian submanifolds in the suspension of a symplectic manifold. The goal is to show that its categorical version is compatible with mirror symmetry and the mutation operation of sheaves.
