Enveloping algebras of generalized H-Hom-Lie algebras

广义H-Hom-李代数的包络代数（英文）

Let H be a Hopf algebra and HYD the Yetter- Drinfeld category over H. First, the enveloping algebra of generalized H-Hom-Lie algebra L, i.e., Hom-Lie algebra L H in the category HYD, is constructed. Secondly, it is obtained that U（L） = T（ L）/L where I is the Hom-ideal of T（L） generated by {ll＇-l_（（-1））·l＇l_0-[l,l＇]｜l,l＇∈L}, and u： L,T（L）/I is the canonical map. Finally, as the applications of the result, the enveloping algebras of generalized H-Lie algebras, i.e., the Lie algebras in the category MyDn and the Hom-Lie algebras in the category of left H-comodules are presented, respectively.

设H是一个Hopf代数,_H^HYD是H上的Yetter-Drinfeld范畴.首先,构造了广义H-Hom-李代数L,即Hom-李代数L是范畴_H^HYD中对象的包络代数.其次,证明了U(L)=T(L)/I,其中I是由{ll'-l_((-1))·l'l_0-[l,l']|l,l'∈L}生成的T(L)的Hom-理想,u:L→T(L)/I是典范同态.最后,作为应用,分别得到了广义H-李代数,即范畴_H^HYD中的李代数和左H-余模范畴中广义H-Hom-李代数的包络代数.
