On Monday July 23 2018 I gave a talk in the Geometry and Topology seminar at the University of Melbourne.

The slides from the talk are available here.

Title:

The algebra and geometry of contact categories

Abstract:

Contact categories, introduced by Ko Honda, are a type of cobordism category related to 3-dimensional contact geometry. Geometrically, they encode contact structures in an elementary combinatorial way. Algebraically, they are related to triangulated categories, A-infinity algebras, Floer homology, and other wholesome fun. In this talk I’ll tell you something about them and report on some recent developments. No knowledge of contact geometry or topology will be assumed.
