我们从 Frobenius 代数的角度研究拟 Hopf 代数及其在某些交换环上的子对象。我们介绍一种涉及 Frobenius 代数的反自同构和 Nakayama 自同构的 Radford 公式,然后从这个角度观察量子代数中的几个结果。此外,还研究了拟Hopf代数作为Frobenius代数的可分性和强可分性。
We study quasi-Hopf algebras and their subobjects over certain commutative rings from the point of view of Frobenius algebras. We introduce a type of Radford formula involving an anti-automorphism and the Nakayama automorphism of a Frobenius algebra, then view several results in quantum algebras from this vantage-point. In addition, separability and strong separability of quasi-Hopf algebras are studied as Frobenius algebras.
