有限von Neumann algebras可测算子代数上连续导子的内禀性

Innerness of continuous derivations on algebras of measurable operators affiliated with finite von Neumann algebras

Shavkat Ayupov, Karimbergen Kudaybergenov

摘要:

本文研究了有限von Neumann代数$S(M)$上所有可测算子的导子.证明了:如果$M$是一个具有忠实正规半有限迹$τ$的有限von Neumann代数,且具有局部测度拓扑$t,$,则每个$t$ -连续导子$D:S(M)\rightarrow S(M)$都是内导子.一个类似的结果是有效的推导代数$S(M,τ)$的$τ$ -可测算子配备的测量拓扑$t_τ$。

英文摘要:

This paper is devoted to derivations on the algebra $S(M)$ of all measurable operators affiliated with a finite von Neumann algebra $M.$ We prove that if $M$ is a finite von Neumann algebra with a faithful normal semi-finite trace $τ$, equipped with the locally measure topology $t,$ then every $t$-continuous derivation $D:S(M)\rightarrow S(M)$ is inner. A similar result is valid for derivation on the algebra $S(M,τ)$ of $τ$-measurable operators equipped with the measure topology $t_τ$.
