Abstract

In this paper, we show that under certain conditions every Lie higher derivation and Lie triple derivation on a triangular algebra are proper, respectively. The main results are then applied to (block) upper triangular matrix algebras and nest algebras.

Keywords: Lie derivation, Lie higher derivation, Lie triple derivation, triangular algebra
