DESCRIPTION:Title: <a href="https://researchseminars.org/talk/TQFT/43/">Hi
 gher S-matrices</a>\nby Theo Johnson-Freyd (Dalhousie University and Perim
 eter Institute) as part of Topological Quantum Field Theory Club (IST\, Li
 sbon)\n\n\nAbstract\nEach fusion higher category has a "framed S-matrix" w
 hich encodes the commutator of operators of complementary dimension. I wil
 l explain how to construct and interpret this pairing\, and I will emphasi
 ze that it may fail to exist if you drop semisimplicity requirements. I wi
 ll then outline a proof that the framed S-matrix detects (non)degeneracy o
 f the fusion higher category. This is joint work in progress with David Re
 utter.\n
