Quantum Double for Quasi-Hopf Algebras

  • S. Majid


We introduce a quantum double quasi-triangular quasi-Hopf algebra D(H) associated to any quasi-Hopf algebra H. The algebra structure is a cocycle double cross-product. We use categorical reconstruction methods. As an example, we recover the quasi-Hopf algebra of Dijkgraaf, Pasquier and Roche as the quantum double Dφ(G) associated to a finite group G and group 3-cocycle φ.
