摘要
研究了一类具有logistic增长的随机SIRS传染病模型.通过Lyapunov函数法,证明了模型全局正解的存在唯一性.给出了模型正解存在平稳分布以及疾病灭绝的充分条件.
A class of stochastic SIRS epidemic model with logistic growth was researched.The existence of a unique of the globel positive solution of the model was proved by using the Lyapunov function method.The sufficient conditions for the existence of a stationary distribution of the positive solutions to the model and the extinction of the disease were obtained.
