摘要

A是Hilbert空间H上的von Neumann代数的CSL子代数.本文证明了,在一定的条件下,A上的Jordan (α,β)-导子是(α,β)-导子,其中α,βA上的两个自同构.还证明了在没有添加任何条件的情况之下,CSL代数上的任意Jordan (α,β)-导子是(α,β)-导子.另外,讨论了von Neumann代数中的CSL子代数上的n次幂(α,β)-映射.

Abstract

Let A be a CSL subalgebra of a von Neumann algebra on a Hilbert space H.It is shown that a Jordan (α,β)-derivation on A is an (α,β)-derivation under a mild condition,where α,β are automorphisms on A.It is also shown that any Jordan (α,β)-derivation on a CSL algebra is an (α,β)-derivation with no additional conditions being assumed.We also investigate the n-th power (α,β)-maps on CSL subalgebras of von Neumann algebras.
