New braided crossed categories and Drinfel’d quantum double for weak Hopf group coalgebras. (English) Zbl 1154.16031

The paper studies properties of weak Hopf group-coalgebras, previously introduced by the authors. A fundamental theorem for weak Hopf group-comodules is proved, and the concept of a Yetter-Drinfeld module over weak crossed structures is defined. The method uses the approach of S. Caenepeel and M. De Lombaerde [Commun. Algebra 34, No. 7, 2631-2657 (2006; Zbl 1103.16024)] to Turaev’s categorical theory. An analog of a Drinfeld quantum double is defined over a weak crossed Hopf group-coalgebra, and it is shown that the category of modules over such a Drinfeld quantum double is isomorphic to the category of Yetter-Drinfeld modules. In this way new classes of braided crossed categories in the sense of Turaev are constructed.
