Picard-Lefschetz theory and dilating C^*-actions

Symplectic Geometry 2017-05-17 v3 K-Theory and Homology

Abstract

We consider C^*-actions on Fukaya categories of exact symplectic manifolds. Such actions can be constructed by dimensional induction, going from the fibre of a Lefschetz fibration to its total space. We explore applications to the topology of Lagrangian submanifolds, with an emphasis on ease of computation.
