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…
Finite-dimensional Pointed or Copointed Hopf algebras over affine racks
Agustín García Iglesias, Cristian Vay
We study the pointed or copointed liftings of Nichols algebras associated to affine racks and constant cocycles for any finite group admitting a principal YD-realization of these r…
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…
