Examples of pointed color Hopf algebras
Nicolas Andruskiewitsch, Ivan Angiono, Dirceu Bagio
We present examples of color Hopf algebras, i.e. Hopf algebras in color categories (braided tensor categories with braiding induced by a bicharacter on an abelian group), related w…
Lifting via cocycle deformation
Nicolás Andruskiewitsch, Iván Angiono, Agustín García Iglesias +2
We develop a strategy to compute all liftings of a Nichols algebra over a finite dimensional cosemisimple Hopf algebra. We produce them as cocycle deformations of the bosonization…
De-equivariantization of Hopf algebras
Iván Angiono, César Galindo, Mariana Pereira
We study the de-equivariantization of a Hopf algebra by an affine group scheme and we apply Tannakian techniques in order to realize it as the tensor category of comodules over a c…
From Hopf algebras to tensor categories
Nicolas Andruskiewitsch, Ivan Angiono, Agustin Garcia Iglesias +2
This is a survey on spherical Hopf algebras. We give criteria to decide when a Hopf algebra is spherical and collect examples. We discuss tilting modules as a mean to obtain a fusi…
