摘要:

M是包含非平凡投影P的单位素环. 利用算子论方法证明了: 如果φ: M→M是非线性Lie中心化子, 则存在λ∈C及映射ξ: M→C满足ξ([A,B])=0(A,B∈M), 使得对任意的X∈M, 有φ(X)=λX+ξ(X)I.

关键词: Lie中心化子, 素环, 非线性

Abstract:

Let M be a unital prime  ring containing a nontrivial projection P. With some methods of operator theory, it is shown that if φ: M→M is a nonlinear Lie ce
ntralizer, then there exist a scalar λ and a map ξ: M→C to meet with ξ([A,B])=0 (A,B∈M) so that φ(X)=λX+ξ(X)I for all X∈M.

Key words: Lie centralizers, prime rings, nonlinear
