Abstract
Let be a Hopf algebra. Any finite-dimensional lifting of arising as a cocycle deformation of defines a twist in the Hopf algebra , 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.
