摘要 设U=Tri(A,M,B)是三角代数,δ,τ为U→U上的两个映射(无可加性或线性假设).利用矩阵分块的方法证明了:如果对任意的a,b∈U,有δ([a,b])=[δ(a),b]+[a,τ(b)],则τ=σ+L,δ=θ+f,其中:σ:U→U是可加导子;L:U→Z(U)是模可加的中心值映射;θ:U→U是关于σ的可加广义导子;f:U→Z(U)是中心值映射,且f([a,b])=0. Let U = Tri( A,M,B) be a triangular algebras,and δ,τ: U → U are two maps( without the additivity or linearity assumption). With the help of decomposing matrix, it was proved that ifδ( [a,b]) = [δ( a),b]+[a,τ( b) ] for all a,b∈U,then τ = σ+L,δ = θ+f,where σ: U→U is an additive derivation; L: U → Z( U) is a modulo additive central-value map; θ: U → U is an additive general derivation relating to σ,f: U→Z( U) is a central-value map,and f( [a,b]) = 0.
