SUMMARY:A fully local extension of Chern-Simons theory
DESCRIPTION:Geometry and Quantum Theory Seminar \nSpeaker: Dan Freed \nTitle: A fully local extension of Chern-Simons theory \nAbstract: The Reshetikhin-Turaev-Witten invariants of 3-manifolds fit into a 3-dimensional topological field theory that also attaches invariants to 2-manifolds and 1-manifolds. It has long been asked to extend to invariants of 0-manifolds as well\, a question that often takes the form: What does Chern-Simons theory attach to a point?. In joint work with Claudia Scheimbauer and Constantin Teleman we use the cobordism hypothesis to construct a fully local version of Chern-Simons theory. We also consider different versions with different tangential structures\, as I will explain.
