一类具有治愈率和非线性发生率的H IV 感染模型的动力学特性
Dynamics of HIV Infection Model with Cure Rate and Nonlinear Incidence Rate
摘要
Abstract
The dynamics of HIV infection model with cure rate and nonlinear incidence rate is investigated .The explicit expression for the basic reproduction number of the model which determines whether the virus dies out or not is obtained.With characteristic equation and Hurwitz criterion , the local stability of the equilibria is analyzed .By constructing a proper Lyapunov function , the global stability of the infection-free equilibrium is derived when the basic reproduction number is less than unity .Using the second additive compound matrix theory,we prove that the endemic equilibrium is globally asymptotically stable when the basic reproduction number is greater than unity .关键词
