Innerness of continuous derivations on algebras of locally measurable operators

A. F. Ber, V. I. Chilin, F. A. Sukochev

摘要:

本文证明了在von Neumann代数$\mathcal{M}$的所有局部可测算子的 *-代数$LS(\mathcal{M})$上的每个关于局部测度拓扑连续的导子都是内必要的.若$\mathcal{M}$是真无限vonNeumann代数,则$LS(\mathcal{M})$上的每个导子都是内导子.另外,证明了取值于局部可测算子的Banach $\mathcal{M}$ -双模的$\mathcal{M}$上的任何导子都是内导子.

英文摘要:

It is established that every derivation continuous with respect to the local measure topology acting on the *-algebra $LS(\mathcal{M})$ of all locally measurable operators affiliated with a von Neumann algebra $\mathcal{M}$ is necessary inner. If $\mathcal{M}$ is a properly infinite von Neumann algebra, then every derivation on $LS(\mathcal{M})$ is inner. In addition, it is proved that any derivation on $\mathcal{M}$ with values in Banach $\mathcal{M}$-bimodule of locally measurable operators is inner.
