Abstract

Let H1H_1 and H2H_2 be Hopf algebras which are not necessarily finite dimensional and α,βAutHopf(H1),γ,δAutHopf(H2)\alpha,\beta \in Aut_{Hopf}(H_1), \gamma,\delta \in Aut_{Hopf}(H_2). In this paper, we introduce a category H1LRH2(α,β,γ,δ){}_{H_1}\mathcal{LR}_{H_2}(\alpha, \beta, \gamma, \delta), generalizing Yetter-Drinfeld-Long bimodules and construct a braided TT-category LR(H1,H2)\mathcal{LR}(H_1,H_2) containing all the categories H1LRH2(α,β,γ,δ)_{H_1}\mathcal{LR}_{H_2}(\alpha, \beta, \gamma, \delta) as components. We also prove that if (α,β,γ,δ)(\alpha, \beta, \gamma, \delta) admits a quadruple in involution, then H1LRH2(α,β,γ,δ){}_{H_1}\mathcal{LR}_{H_2}(\alpha, \beta, \gamma, \delta) is isomorphic to the usual category H1LRH2{}_{H_1}\mathcal{LR}_{H_2} of Yetter-Drinfeld-Long bimodules.
