BiHom Hopf algebras viewed as Hopf monoids
Gabriella Böhm, Joost Vercruysse
We introduce monoidal categories whose monoidal products of any positive number of factors are lax coherent and whose nullary products are oplax coherent. We call them $\mathsf{Lax…
Yetter-Drinfeld modules over weak multiplier bialgebras
Gabriella Böhm
We continue the study of the representation theory of a regular weak multiplier bialgebra with full comultiplication, started in arXiv:1306.1466, arXiv:1311.2730. Yetter-Drinfeld m…
Comodules over weak multiplier bialgebras
Gabriella Böhm
This is a sequel paper of arXiv:1306.1466 in which we study the comodules over a regular weak multiplier bialgebra over a field, with a full comultiplication. Replacing the usual n…
Hopf Algebroids
Gabriella Böhm
This is a preprint version of a chapter for Handbook of Algebra.
Galois extensions over commutative and non-commutative base
Gabriella Böhm
This paper is a written form of a talk. It gives a review of various notions of Galois (and in particular cleft) extensions. Extensions by coalgebras,bialgebras and Hopf algebras (…
Integral theory for Hopf Algebroids
Gabriella Böhm
The theory of integrals is used to analyse the structure of Hopf algebroids, introduced in math.QA/0302325. We prove that the total algebra of the Hopf algebroid is a separable ext…
