具有标准发生率和因病死亡率的离散SIRS传染病模型的全局稳定性
Global Stability of a Discrete SIRS Epidemic Model with Standard Incidence and Disease-induced Mortality
摘要
Abstract
We study a discrete SIRS epidemic model with standard incidence and disease-induced mortality. By using the method of discrete Lyapunov function,the globally asymptotical stability of disease-free equilibrium and endemic equilibrium for the model is established. Particularly,when disease-induced death rate equals to zero,it is shown that the endemic equilibrium is globally asymptotically stable if and only if the basic reproduction number is greater than one.关键词
