Title:Hochschild cohomology and extended field theories
Seminar:Noncommutative Geometry Seminar
Speaker:Gregory Ginot, UPMC Paris 6
Abstract:
I will discuss the relationship in between Hochschild homology and Lurie's cobordism hypothesis. I will explain how to associate a higher category to a CDGA and how to build a TFT from this. I will then explain why the invariants of manifolds produced this way are given by Hochschild homology and its analogues.
