【摘   要】   借助双模结构证明了三角代数上的每一个双Lie triple导子[δ]都可以分解为inner双导子、 extremal双导子以及中心映射之和。作为应用,在上三角矩阵代数和套代数的双Lie triple导子上得到了同样结论。

Bi-Lie Triple Derivation on Triangular Algebras

Liang Xinfeng, Guo Haonan

(Anhui University of Science and Technology, Huainan 232000, China)

【Abstract】    This paper proves that under mild conditions, every bi-Lie triple derivation on triangular algebra can be decomposed into the sum of an inner biderivation, an extremal biderivation, and a central mapping using a faithful bimodule structure. As applications, the same conclusions are obtained on the bi-Lie triple derivations of upper triangular matrix algebras and nest algebras.

【Key words】     triangular algebra; bi-Lie triple derivation; upper triangular algebras; nest algebras
