研究具有时滞的媒介传播的传染病模型.确定了疾病是否流行的阈值R0.当R0≤1时,通过构造Lyapunov泛函证明了系统无病平衡点的全局渐近稳定性.
To study the epidemiological model of epidemic with delay, we determine the threshold R0 of the prevalence of disease.When R0≤1, we prove the global asymptotic stability of the system disease-free equilibrium by constructing Lyapunov functional.
