Global dynamics of the epidemiological model of hepatitis C virus infection
摘要:
主要研究了具有标准发生率的丙型肝炎流行病动力学模型.通过构造适当的Lyapunov函数,得到模型无病平衡点的全局稳定性以及特定条件下地方病平衡点的全局稳定性,即如果R0≤1,模型的无病平衡点是全局渐近稳定的;如果R0>1且μ=0,则地方病平衡点是全局渐近稳定的.
The epidemiological dynamics model of hepatitis C with standard incidence was mainly studied. By constructing the appropriate Lyapunov functions, the global stability of the model’s disease-free equilibrium point and endemic equilibrium point under certain conditions are obtained, that is, if the basic reproductive number R0≤1, the disease-free equilibrium of the model is globally asymptotically stable;if R0>1 and μ=0, the endemic equilibrium of the model is globally asymptotically stable.
