Strictification of weakly equivariant Hopf algebras
Jennifer Maier, Thomas Nikolaus, Christoph Schweigert
A weakly equivariant Hopf algebra is a Hopf algebra A with an action of a finite group G up to inner automorphisms. We show that each weakly equivariant Hopf algebra can be replace…
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…
Modular categories from finite crossed modules
Jennifer Maier, Christoph Schweigert
It is known that finite crossed modules provide premodular tensor categories. These categories are in fact modularizable. We construct the modularization and show that it is equiva…
