Let A be a multiplicative Hom-associative algebra and L a multiplicative Hom-Lie algebra together with surjective twisting maps. We show that if A is a sum of two commutative Hom-associative subalgebras, then the commutator Hom-ideal is nilpotent. Furthermore, we obtain an analogous result for Hom-Lie algebra L extending Kegel's Theorem. Finally, we discuss the Hom-Lie ideal structure of a simple Hom-associative algebra A by showing that any non-commutative Hom-Lie ideal of A must contain [A, A]. 相似文献

设H为Hopf代数,本文介绍双Hom李H-伪超代数的概念,这类代数是Hom李伪代数的自然推广,也是双Hom李超代数的特例.我们揭示双Hom李H-伪超代数的构造定理,重新修订双Hom李H-伪超代数概念的等价性,并且利用双Hom模的系数考虑双Hom李H-伪超代数的上同调理论. 相似文献
