摘要 研究了一类具有指数发生率的离散SIS传染病模型的动力学性态.利用再生矩阵的方法定义了模型的基本再生数;对模型进行分析得到平衡点的存在性和稳定性,同时也得到了模型的持久性;通过参数赋值,利用数值模拟方法对平衡解的相关结果进行了验证. In this paper,the discrete-time SIS epidemic model with exponential occurrence rate is investigated.Using the renewable matrix method,we defined the basic reproductive number;The existence and stability conditions of equilibria and the persistence of SIS model are discussed.Numerical simulations are conducted to demonstrate our theoretical results.
