We investigate the property of being Frobenius for some functors strictly related with Hopf modules over a bialgebra and how this property reflects on the latter. In particular, we characterize one-sided Hopf algebras with anti-(co)multiplicative one-sided antipode as those for which the free Hopf module functor is Frobenius. As a by-product, this leads us to relate the property of being an FH-algebra (in the sense of Pareigis) for a given bialgebra with the property of being Frobenius for certain naturally associated functors.

Hopf 模块、Frobenius 函子和(单边)Hopf 代数

我们研究了一些与双代数上的 Hopf 模块严格相关的函子的 Frobenius 性质,以及该性质如何反映后者。特别地,我们将具有反(共)乘单边对映体的单边 Hopf 代数表征为自由 Hopf 模函子是 Frobenius 的那些。作为副产品,这导致我们将给定双代数的 FH 代数性质(在 Pareigis 的意义上)与某些自然关联函子的 Frobenius 性质联系起来。
