Elementary Operators on Standard Operator Algebras

We present a new simple proof of the structural result for elementary operators on standard operator algebras. Using the idea of this short proof we can characterize surjective maps between standard operator algebras having a certain multiplicativity-like property appearing in the abstract definition of elementary operators of length one. In particular, we show that such maps are automatically additive.

检测模糊控制器是否有隐匿缺陷的一种方法

目的:检测模糊控制系统中的模糊控制器是否有隐匿的缺陷。方法:通过分析Zadeh算子与Einstain算子及2种广义算子之间的内在联系,给出了Zadeh算子与Einstain算子及2种广义算子之间的隶属关系,分别用各类算子检测模糊控制系统中的模糊控制器。结果:在检测模糊控制系统中的模糊控制器是否有隐匿的缺陷时,广义算子(如Einstain算子)是一种非常有效的工具。结论:广义算子(如Einstain算子)能检测出模糊控制系统中的模糊控制器是否有隐匿缺陷。     

关于IVIFS算子与IFS算子关系的讨论

Atanassov教授在给出区间教直觉模糊集算子的定义以后曾给出断语:直觉模糊集算子满足的结论,都可以推广到相应的区问数直党模糊集算子.本文详细分析多条直觉模糊集算子的性质与相应区间数直党模糊集算子的性质之间的关系,证明这些直觉模糊集算子的性质都不能推广到区间数直党模糊集算子,因而对Atanassov的论断进行了澄清.     

Operator integrals and sesquilinear forms

We consider various systematic ways of defining unbounded operator valued integrals of complex functions with respect to (mostly) positive operator measures and positive sesquilinear form measures, and investigate their relationships to each other in view of the extension theory of symmetric operators. We demonstrate the associated mathematical subtleties with a physically relevant example involving moment operators of the momentum observable of a particle confined to move on a bounded interval.     

m-增生算子的紧扰动的一些映射定理

本文在实Banach空间中证明了几个m-增生算子紧扰动的映射定理，它们分别改进了Kartsatos(1987，1993)，Morales(1991)和何震等人(1992)的结果。     

Truncation method for operators with disconnected essential spectrum

In this short paper, the usage of truncation method to get information about essential spectrum of bounded as well as semi-bounded linear operators on separable Hilbert spaces, is investigated. In addition to this, the problem of predicting the gaps in the essential spectrum of self-adjoint operators, linear algebraically is also considered.     

从矩阵迹关系过渡到算子迹关系的一个通用方法

本文给出了一个将矩阵迹的不等式推广为Ｈｉｌｂｅｒｔ空间中算子迹的不等式的方法，并用它较简捷地将矩阵论中Ｂｅｌｌｍａｎ问题的已有结果以及其它一些矩阵迹的不等式推广为算子迹的相应不等式。
