算子空间理论在套代数双模中的应用

Applications of operator space theory to nest algebra bimodules

G. K. Eleftherakis

摘要:

最近Blecher和Kashyap将von Neumann代数上的W* 模的概念推广到算子代数是希尔伯特空间上的σ-弱闭算子代数的情形。他们称这些模块为弱 * 操纵模块。刻画了套代数上的弱 * 装配模。证明了Y是套代数Alg(M)上的右弱 * 操纵模当且仅当存在Y和套代数Alg(N)的完全等距正规表示,使得Alg(N)(Y)Alg(M)\subset(Y),而(Y)由M到N的连续套同态实现。我们描述了连续CSL同态所保持的一些性质。

英文摘要:

Recently Blecher and Kashyap have generalized the notion of W* modules over von Neumann algebras to the setting where the operator algebras are σ- weakly closed algebras of operators on a Hilbert space. They call these modules weak* rigged modules. We characterize the weak* rigged modules over nest algebras . We prove that Y is a right weak* rigged module over a nest algebra Alg(M) if and only if there exists a completely isometric normal representation ϕof Y and a nest algebra Alg(N) such that Alg(N)ϕ(Y)Alg(M) \subset ϕ(Y) while ϕ(Y) is implemented by a continuous nest homomorphism from M onto N. We describe some properties which are preserved by continuous CSL homomorphisms.
