摘要：Let g be a complex semisimple Lie algebra, b be a Borel subalgebra of g and n = [b, b] denote the maximal nilpotent subalgebra of g. In this article, we prove that every generalized Lie triple derivation of b can be written as the sum of a Lie triple derivation and a block diagonal map. We also show that every generalized Lie triple derivation for n of each classical complex simple Lie algebra is the sum of a Lie triple derivation and a homothety.
