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.

通过Natter-Drinfeld-Long Bimodules编织T类的构造

\(H_1 \)\(H_2 \)为Hopf代数,它们不一定是有限维的,而\(\ alpha,\ beta \ in Aut_ {Hopf}(H_1),\ gamma,\ delta \ in Aut_ {Hopf} (H_2)\)。在本文中,我们介绍了一个类别\(_ {H_1} \ mathcal {LR} _ {H_2}(\ alpha,\ beta,\ gamma,\ delta)\),推广了Butter–Drinfeld–Long双模并构造了一个编织Ť -category \(\ mathcal {LR}(H_1,H_2)\)包含所有的类别\(_ {H_1} \ {mathcal LR} _ {H_2}(\α,\-β,\γ,\三角洲)\ )作为组件。我们还证明了,如果\((\ alpha,\ beta,\ gamma,\ delta)\)允许四次对合,那么\(_ {H_1} \ mathcal {LR} _ {H_2}(\ alpha,\ beta,\ gamma,\ delta)\)与通常的类别\(_ {H_1} \ mathcal {LR} _ {H_2 } \)的Yetter–Drinfeld–Long双模。
