A characterization of partial ξ-Lie derivable maps on triangular algebras
摘要
Abstract
Using method of algebra decomposition, partial ξ-Lie derivable map on a triangular algebra u=-Tri(A,M,B) is studied. It is proved that if for every A∈ A, there exists a integer k such that kIA--A is invertible,then a linear map on Uis a derivation if and only if it is a partial ξ-Lie derivable map. As an application, it is proved that inner derivations on nontrivial nest algebras and partialξ-Lie derivable maps are the same.关键词
