Spectral Properties and Positivity of Flows in Infinite Networks with Dynamic Boundary Control Nodes
《Journal of Systems Science and Information》2009年第4期319-325,共7页Xuelian Jin Fu Zheng Ming Fang Chao Gao 
In this paper we study transport processes on infinite networks with dynamic boundary control nodes. These flows can be modeled by operator semigroups on a suitable Banach space. Using functional analytical and graph ...

Exponential Stability Analysis of a Markovian Deteriorating System被引量:1
《Journal of Systems Science and Information》2009年第2期129-140,共12页Yinghua Shen Yufeng Zhang Aidong Jin 
The reliability of a complex system passes through a gradual deterioration until at some critical level, the system fails completely. The study of the exponential stability of such a system requires the application of...

A Perturbation Theorem for Exponentially Bounded C-semigroups
《Chinese Science Bulletin》1994年第21期1770-1773,共4页姚景齐 
Project supported by the National Natural Science Foundation of China.
Let (X;‖ ‖) be a Banach space. By B(X) we denote the set of all bounded linear operators in X. Let C∈B(X) be injective.A strongly continuous family of bounded operators {S(t); t≥0} is called an exponentially bound...
