Resumen:
Let V be a Yetter-Drinfeld module over a cosemisimple Hopf algebra H such that the Nichols algebra B(V) is finite-dimensional.We present a strategy, based on cocycle deformations, to compute all liftings of V; that is all Hopf algebras L with gr(L) = B(V) #H , where gr(L) stands for the graded Hopf algebra associated to the coradical filtration of L.
