辫子Hom-李代数的中心不变量和包络代数代数

Central invariants and enveloping algebras of braided Hom-Lie algebras

Shengxiang Wang, Xiaohui Zhang, Shuangjian Guo

摘要:

设$(H,α)$是Monoidal Hom-霍普夫代数,$^{H}_{H}\mathcal{HYD}$是$(H,α)$上的Hom-Yetter-Drinfeld范畴.本文首先给出了辫子Hom-李代数的定义,并证明了$^{H}_{H}\mathcal{HYD}$中的每一个幺半群Hom-代数都可以生成一个辫子Hom-李代数。其次,证明了如果$(A,β)$是两个$H$ -交换Monoidal Hom-子代数的和,则$A$的换位子Hom-理想$[A,A]$是幂零的.作为广义李代数的推广,我们研究了辫子Hom-李代数的中心不变量.最后,我们构造了辫子Hom-李代数的包络代数代数,并证明了这种包络代数代数是$H$ -余交换的Hom-Hopf代数.

英文摘要:

Let $(H,α)$ be a monoidal Hom-Hopf algebra and $^{H}_{H}\mathcal{HYD}$ the Hom-Yetter-Drinfeld category over $(H,α)$. Then in this paper, we first introduce the definition of braided Hom-Lie algebras and show that each monoidal Hom-algebra in $^{H}_{H}\mathcal{HYD}$ gives rise to a braided Hom-Lie algebra. Second, we prove that if $(A,β)$ is a sum of two $H$-commutative monoidal Hom-subalgebras, then the commutator Hom-ideal $[A,A]$ of $A$ is nilpotent. Also, we study the central invariant of braided Hom-Lie algebras as a generalization of generalized Lie algebras. Finally, we obtain a construction of the enveloping algebras of braided Hom-Lie algebras and show that the enveloping algebras are $H$-cocommutative Hom-Hopf algerbas.
