Representation Theory and Mathematical Physics Seminar: Perturbative Chern-Simons invariants from quantum BV-BFV formalism.

I will report on recent developments in the computation of Perturbative Chern-Simons invariants via cutting and gluing in the quantum BV-BFV formalism. In particular, I will present results on theta-invariants of lens spaces that agree with earlier works of Kuperberg, Thurston and Lescop. This is ongoing joint work with A. Cattaneo and P. Mnev.
