一类具有阶段结构和潜伏期时滞的SEI模型的全局动力学性态

Global Dynamics of an SEI Epidemic Model with Stage Structure and Latent Period

研究一类具有潜伏期时滞、阶段结构和标准发生率的SEI模型，利用比较定理和单调迭代的方法，分别得到无病平衡点和地方病平衡点全局吸引的充分条件．

An SEI epidemic model with a time delay describing the latent period, stage structure and standard incidence rate is investigated. Using an iteration technique and comparison arguments,sufficient conditions are derived for the global attractivity of the disease free equilibrium and the endemic equilibrium respectively.
