Modular invariant Frobenius algebras from ribbon Hopf algebra automorphisms
Jurgen Fuchs, Christoph Schweigert, Carl Stigner
For any finite-dimensional factorizable ribbon Hopf algebra H and any ribbon automorphism omega of H, we establish the existence of the following structure: an H-bimodule F_omega a…

Equivariant Modular Categories via Dijkgraaf-Witten Theory
Jennifer Maier, Thomas Nikolaus, Christoph Schweigert
Based on a weak action of a finite group J on a finite group G, we present a geometric construction of J-equivariant Dijkgraaf-Witten theory as an extended topological field theory…
