Lifting via cocycle deformation
Andruskiewitsch, Nicolás; Angiono, Iván Ezequiel; García Iglesias, Agustín; Masuoka, Akira; Vay, Cristian Damián (2014)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 ...
