一类具有脉冲免疫的时滞SIRS传染病模型的全局分析
Global Analysis of a Delay SIRS Epidemic Disease Model with Pulse Vaccination
摘要
Abstract
An SIRS epidemic disease model with pulse vaccination and integral delays was considered, and dynamics behaiors of the model under pulse vaccination were analyzed. By use of the discrete dynam-ical system determined by the stroboscopic map, an“infection-free” periodic solution was obtained and it iwas shown that the‘infection-free’ periodic solution was asymptotic stability. Then, it was proved that when some parameters of the model were in appropriate condictions, the ‘infection-free’ periodic sollu-tion was globally attractive. Futher, with the theory on delay functional and impulsive differential equa-tion, sufficient condiction with time delay for permanence of the system was given. At the same time, the condition of the global attractivity of the model was obtained.关键词
