【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。

【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
