摘    要:设A是B(H)的子代数,ψ是A到A的线性映射,且对A中的每个正交投影算子p,有ψ(p)(kerp)ranp,则称ψ是A到A的P-核值保持映射,本文主要得到如下结果:每个2-非绕的半素环上的广义Jordan导子都是广义导子;每个VonNeumann代数上的范数拓扑连续的P-核值保持映射是广义内导子.

关 键 词:Von Neumann代数,2-非绕的半素环.P-核值保持映射,广义导子,广义内导子

Abstract:Let A be an operator subalgebra in B(H), we say that a linear mapping ψ:AA is a P-pre serving kernel into range mapping if ψ(p)( ker p)  ran p for any self-adjoint projection operator p in A. In this paper, we obtain the following main results: Every generalized Jordan derivation on 2-torsion free semiprime rings is a generalized derivation; Every norm-continuous linear mapping of P-preserving kernel into range on Von Neumann algebras is a generalized inner derivation.
Keywords:Von Neumann algebras   2-torsion free semiprime ring   P-preserving kernel into range mapping   Generalized derivation   Generalized inner derivation
