摘要
Let T(n, R) be the Lie algebra consisting of all n× n upper triangular matrices over a commutative ring R with identity 1 and M be a 2-torsion free unital T(n, R)-bimodule. In this paper, we prove that every Lie triple derivation d : T(n, R) →M is the sum of a Jordan derivation and a central Lie triple derivation.
