Crossed extensions of the corepresentation category of finite supergroup algebras
Mejía Castaño, Adriana; Mombelli, Martín (2015)We present explicit examples of finite tensor categories that are C2-graded extensions of the corepresentation category of certain finite-dimensional non-semisimple Hopf algebras -
Invertible bimodule categories over the representation category of a Hopf algebra
Femić, Bojana; Mejía Castaño, Adriana; Mombelli, Juan Martín (2014-02-12)For any finite-dimensional Hopf algebra H we construct a group homomorphism BiGal (H) → BrPic(Rep(H)), from the group of equivalence classes of H-biGalois objects to the group of equivalence classes of invertible exact ...
