摘要
考虑了一类具有空间异质和反应扩散的SVIR传染病模型.当基本再生数等于1时,假定扩散系数为常数,证明了系统的无病平衡态是全局渐近稳定的.
A diffusive SVIR epidemic model with spatial heterogeneity is considered.When the basic reproduction number is equal to 1,assuming the diffusion coefficient is constant,the global stability of the disease-free steady state is established.
