Title: Quasi-symplectic groupoids and the Moore-Tachikawa conjecture
Abstract: I will briefly review Moore and Tachikawa’s conjectural topological quantum field theory (TQFT), as well as the Poisson geometry underlying its formulation. This will lead to an outline of recent, affirmative evidence for the conjecture. I will also detail a systematic association of TQFTs to certain quasi-symplectic Lie groupoids. A distinguished role will be played by the partial Grothendieck-Springer resolutions and their Poisson-geometric relatives. This represents joint work with Maxence Mayrand.
