Resumen:
Let H be a Hopf algebra. Any finite-dimensional lifting of (Formula presented.) arising as a cocycle deformation of (Formula presented.) defines a twist in the Hopf algebra (Formula presented.), via dualization. We follow this recipe to write down explicit examples and show that it extends known techniques for defining twists. We also contribute with a detailed survey about twists in braided categories.
