Corepresentation theory of universal cosovereign Hopf algebras
Julien Bichon
We determine the corepresentation theory of universal cosovereign Hopf algebras, for generic matrices over an algebraically closed field of characteristic zero.

Hopf-Galois Systems
Julien Bichon
We introduce the concept of Hopf-Galois system, a reformulation of the notion of Galois extension of the base field for a Hopf algebra. The main feature of our definition is a gene…

Cosemisimple Hopf algebras with antipode of arbitrary finite order
Julien Bichon
We show that there exists cosemisimple Hopf algebras of arbitrary finite even order. We also discuss the Schur indicator for such Hopf algebras.
