【摘要】 本文研究具有分布时滞的病毒感染模型的动力学性质.构建该模型,基于Lyapunov泛函分析方法,研究该系统平衡点的全局稳定性.分别得到该系统无病平衡点和感染平衡点全局稳定的充分条件.

【Abstract】 This paper is concerned with the study of dynamic analysis of the virus infection systems considering the effect of the time delay.First,a mathematical model of the virus infection systems with distributed time delay is proposed and then,based on Lyapunov functional method,the global stability of the steady states of the system is investigated.Some sufficient conditions for the global stability of the infection-free solution and infection solution are respectively derived.
