Yetter-Drinfeld-Long bimodules are modules
Let be a finite-dimensional bialgebra. In this paper, we prove that the category of Yetter-Drinfeld-Long bimodules, introduced by F. Panaite, F. Van Oystaeyen (2008), is isomorphic to the Yetter-Drinfeld category over the tensor product bialgebra as monoidal categories. Moreover if is a finite-dimensional Hopf algebra with bijective antipode, the isomorphism is braided. Finally, as an application of this category isomorphism, we give two results.
