In a previous paper [4] we tried to build the basic theory of unbounded Tomita's observable algebras called T†-algebras which are related to unbounded operator algebras, especially unbounded Tomita-Takesaki theory, operator algebras on Krein spaces, studies of positive linear functionals on *-algebras and so on. And we defined the notions of regularity, semisimplicity and singularity of T†-algebras and characterized them. In this paper we shall proceed further with our studies of T†-algebras and investigate whether a T†-algebra is decomposable into a regular part and a singular part.

富田可观察代数 II 的无界推广
在之前的一篇论文[4]中,我们试图建立无界 Tomita 的可观测代数的基础理论,称为T † -代数,它与无界算子代数有关,特别是无界 Tomita-Takesaki 理论,Kerin 空间上的算子代数,正线性泛函的研究*-代数等。定义了T † -代数的正则性、半单纯性和奇异性的概念并刻画了它们。在本文中,我们将进一步研究T † -代数,并研究T † -代数是否可分解为正则部分和奇异部分。
