摘要:
为了研究有限的医疗资源对传染病传播影响,本文考虑了一个SIR传染病模型,并着重分析了模型的Bogdanov-Takens分支问题.结果表明,当基本再生数等于一个子阈值时,模型将出现非常复杂的分支现象.此时,模型惟一的平衡点为余维2尖点.
Abstract:
In this paper，a SIR epidemic model is proposed to understand the impact of limited medical resource on infectious disease transmission， and Bogdanov-Takens bifurcation is analyzed． Our results suggest that the model may exhibit vital dynamics when the basic reproduction number R0 is equal to a subthreshold value and the unique equilibrium is a cusp of codimension 2．
