Resumen:
Let H be a Hopf algebra. Any finite-dimensional lifting of V∈HH arising as a cocycle deformation ofA=𝔅(V)#H defines a twist in the Hopf algebra A∗, viadualization. We follow this recipe to write down explicit examples and showthat it extends known techniques for defining twists. We also contribute with adetailed survey about twists in braided categories.
