摘要: 在3-李代数上定义T-导子的概念,得到了3-李代数的T-导子李代数TDer(L),对T-导子代数的结构进行了研究,并讨论了T-导子代数与导子代数和内导子代数的关系,证明了内导子代数是T-导子代数的理想在特征不为5的域F上的Perfect 3-李代数,它的内导子代数及导子代数在T-导子代数的中心化子为零.

关键词: 3-李代数, T-导子, 导子, 内导子

Abstract: The T-derivations of 3-Lie algebras,T-derivation Lie algebra TDer(L),and its structure were studied.The relations between TDer(L)and Der(L),ad(L)were discussed.It is proved that the inner derivation algebra ad(L)is an ideal of TDer(L).If L is a perfect 3-Lie algebra over a field F with Char F≠5,centralizers of derivation algebra and inner derivation algebra in TDer(L)are both zero.

Key words: 3- Lie algebra, T-derivation, derivation, inner derivation
