Abstract
Let \(H_1\) and \(H_2\) be Hopf algebras which are not necessarily finite dimensional and \(\alpha ,\beta \in Aut_{Hopf}(H_1),\gamma ,\delta \in Aut_{Hopf}(H_2)\). In this paper, we introduce a category \(_{H_1}\mathcal {LR}_{H_2}(\alpha ,\beta ,\gamma ,\delta )\), generalizing Yetter–Drinfeld–Long bimodules and construct a braided T-category \(\mathcal {LR}(H_1,H_2)\) containing all the categories \(_{H_1}\mathcal {LR}_{H_2}(\alpha ,\beta ,\gamma ,\delta )\) as components. We also prove that if \((\alpha ,\beta ,\gamma ,\delta )\) admits a quadruple in involution, then \(_{H_1}\mathcal {LR}_{H_2}(\alpha ,\beta ,\gamma ,\delta )\) is isomorphic to the usual category \(_{H_1}\mathcal {LR}_{H_2}\) of Yetter–Drinfeld–Long bimodules.
