庞加莱指数在一个带有接种疫苗的SIS流行病模型中的应用(英文)

An Aplication of Poincaré Index to an SIS Epidemic Model with Vaccination

  • 摘要: 给出一个带有接种疫苗的SIS流行病模型,并对它进行了分析,得出该模型有3个稳定点,其中1个无病平衡点及2个染病平衡点.

     

    Abstract: An SIS epidemic model with vaccination and temporary immunity is studied.The analyzing result shows that the model has three equilibria,where one is the disease-free equilibrium and two are epidemic equilibrium.
