Quotients and Hopf Images of a Smash Coproduct

Julien Bichon

We describe the Hopf algebra quotients and Hopf images of the smash coproduct of a group algebra by the algebra of functions on a finite group.

Half-liberated real spheres and their subspaces

Julien Bichon

We describe the quantum subspaces of Banica-Goswami's half-liberated real-spheres, showing in particular that there is a bijection between the symmetric ones and the conjugation st…

Graded twisting of categories and quantum groups by group actions

Julien Bichon, Sergey Neshveyev, Makoto Yamashita

Given a Hopf algebra graded by a discrete group together with an action of the same group preserving the grading, we define a new Hopf algebra, which we call the graded twistin…
