Yana Ding, Jiankui li

摘要:

设A是具有非平凡幂等元e的单位代数,f=1-e.假设A满足:对于A中的每个x,exe.eAf={0}=fAe.exe意味着exe=0,eAf.fxf={0}=fxf.fAe意味着fxf=0。本文给出了A上的Lie n-导子满足形式λ =d+δ+γ的充分条件,其中d是A上的导子,δ是A上的奇异Jordan导子,γ是从A到中心Z(A)的线性映射,在A的所有n-1阶算子上为零.特别地,我们还讨论了A上的Lie n-导子是标准的(必要和)充分条件,即δ =d+γ。

英文摘要:

Let A be a unital algebra with a nontrivial idempotent e, and f=1-e. Suppose that A satisfies that exe.eAf={0}=fAe.exe implies exe=0 and eAf.fxf={0}=fxf.fAe implies fxf=0 for each x in A. We obtain the (necessary and) sufficient conditions for a Lie n-derivation ϕ on A to be of the form ϕ=d+δ+γ, where d is a derivation on A, δ is a singular Jordan derivation on A and γ is a linear mapping from A into the centre Z(A) vanishing on all (n-1)-th commutators of A. In particular, we also discuss the (necessary and) sufficient conditions for a Lie n-derivation ϕ on A to be standard, i.e., ϕ=d+γ.
