建立了一类包含药物敏感型和耐药型毒株的HIV感染模型,并且研究了具有饱和发生率和分布潜伏时滞感染模型的动力学行为.得到了模型解的非负性和有界性,以及平衡点的存在性.通过使用线性化方法,构造Lyapunov函数和运用动力系统持续性理论,建立平衡点的局部和全局稳定性,以及模型一致持续性的阈值准则.进一步,数值模拟表明正平衡点全局渐近稳定.
This paper establishes an HIV infection model
which includes wild-type and drug-resistant strains
and the dynamic behavior of infection model with saturated incidence and distributed delays is investigated. The nonnegativity and boundedness of solutions
and the existence of equilibria are obtained. The threshold criteria for the local and global asymptotic stability of equilibria and the uniform persistence of the model are established by using the linearization method
constructing Lyapunov functions and applying the theory of persistence in dynamical systems. Moreover
the numerical examples illustrate that the positive equilibrium may be globally asymptotically stable.
