Generalized Yetter-Drinfeld modules, the center of bi-actegories and groupoid-crossed braided bicategories

Ryan Aziz, Joost Vercruysse

We study the notion of the -center of a -biactegory (or bimodule category) , relative to an op-monoidal fun…

Globalization and the biactegory of partial modules

Eliezer Batista, William Hautekiet, Joost Vercruysse

We show that the category of partial modules over a Hopf algebra is a biactegory (a bimodule category) over the category of global -modules. The corresponding enrichment of…

Dualities for universal (co)acting Hopf monoids

Ana Agore, Alexey Gordienko, Joost Vercruysse

In general, universal (co)measuring (co)monoids and universal (co)acting bi/Hopf monoids, which prove to be a useful tool in the classification of quantum symmetries, do not always…

Lifting of locally initial objects and universal (co)acting Hopf algebras

Ana Agore, Alexey Gordienko, Joost Vercruysse

The universal (co)acting bi/Hopf algebras introduced by Yu. I. Manin, M. Sweedler and D. Tambara, the universal Hopf algebra of a given (co)module structure, as well as the univers…

Towards a classification of simple partial comodules of Hopf algebras

Eliezer Batista, William Hautekiet, Paolo Saracco +1

Making the first steps towards a classification of simple partial comodules, we give a general construction for partial comodules of a Hopf algebra \(H\) using central idempotents…

Everybody knows what a normal gabi-algebra is

Johannes Berger, Paolo Saracco, Joost Vercruysse

Let A be a k-algebra over a commutative ring k. By the renowned Tannaka-Krein reconstruction, liftings of the monoidal structure from k-modules to A-modules correspond to bialgebra…
