Frobenius–Schur indicators and the mapping class group of the torus
The Turaev–Viro state sum invariant can be extended to 3-manifolds with free boundaries. We use this fact to describe generalized Frobenius–Schur indicators as Turaev–Viro invariants of solid tori. This provides a geometric understanding of the SL (2 , Z) -equivariance of these indicators. © 2022, T...
