Resumen:
We establish a bijective correspondence between gauge equivalence classes of dynamical twists in a finite-dimensional Hopf Algebra H based on a finite Abelian group A and equivalence classes of pairs (K, {Vλ} λ∈A), where K is an H-simple left H-comodule semisimple algebra and {Vλ} λ∈A is a family of irreducible representations satisfying certain conditions. Our results generalize the results obtained by Etingof and Nikshych on the classification of dynamical twists in group algebras
