设4为有单位且包含一非平凡幂等元的环,M为A双模.称δ:A→M为Lie可导映射(无可加或连续假设),若δ([A,B])=[δ(A),B]+[A,δ(B)],VA,B∈A.在一定条件下该文证明了Lie可导映射6具有形式δ(A)=τ(A)+f(A),其中τ:A→M是可加导子,f是从A到M的中心且满足f([A,B])=0,VA,B∈A的映射.由此刻画了因子VOYINeuamnn代数和套代数上的Lie可导映射.
Let .4 be a unital algebra, and let M be an A-bimodule. We say (δ: A → 2t4 is a Lie derivable map if it (with no assumption of additivity and continuity) satisfies δ([A, B]) = [δ(A), B] + [A, (δ(B)] for all A, B ∈4. Under some condition, we show that d is of the form 5(A) = -c(A) + f(A), where ∈: A →4 M is an additive derivation and f is a map from 4 into the center of AJ with f([A,B]) = 0 for all A, B ∈4. As its application, we characterize Lie derivable maps on factor von Neumann algebras and nest algebras.
