Lifting via cocycle deformation

Quantum Algebra 2013-07-18 v2 Rings and Algebras

Abstract

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 of these two. In parallel, we study the shape of any such lifting.
