本文引入了广义H-Hom-Lie代数的定义,Yetter-Drinfeld范畴中的Hom-Lie代数 ),并由H-Hom-结合代数得到广义H-Hom-李代数(即,中的Hom-associative代数 )和广义H-Lie代数(即,李代数 )的情况下。证明了如果A是两个H-交换Hom-结合子代数的和,则A的H-交换子Hom-理想是幂零的。最后,我们用与H-代数相似的方法描述了H-Hom-结合代数的H-Hom-Lie理想结构。
In this paper, we introduce the definition of generalized H-Hom–Lie algebras (i.e., Hom-Lie algebras in the Yetter–Drinfeld category ) for any Hopf algebra H, and obtain generalized H-Hom-Lie algebras from H-Hom-associative algebras (i.e., Hom-associative algebras in ) and generalizedH-Lie algebras (i.e., Lie algebras in ), respectively. We show that if A is a sum of two H-commutative Hom-associative subalgebras, then the H-commutator Hom-ideal of A is nilpotent. Finally, we describe the H-Hom-Lie ideal structures of the H-Hom-associative algebras by analogy with that of H-algebras.
