Legendrian fronts in contact topology

Princeton/IAS Symplectic Geometry Seminar
Topic:Legendrian fronts in contact topology
Speaker:Roger Casals
Affiliation:Massachusetts Institute of Technology
Date:Friday, November 13
Time/Room:2:00pm - 3:00pm/S-101

In this talk we focus on Legendrian presentations of Weinstein manifolds; in particular, we discuss loose Legendrian embeddings and their absolute analogues, flexible Weinstein manifolds and overtwisted contact structures. The required definitions and necessary results will be provided. In the first part, we present a dictionary between Legendrian fronts and adapted open books decompositions. In the second part, we explore applications to Weinstein cobordisms and biLefschetz fibrations with Am–Milnor fibres. This is joint work with E. Murphy.
