摘要
Abstract
The HIV infection in vivo model with time delay is studied, which incorporates the duration for the infected T* cells to release the virus as the delay parameter.The global stability of the boundary equilibria is obtained by using the Routh-Hurwitz criteria,constructing Lyapunov function and the nonnegative invariance analysis of the system.And the existence of the threshold τ0 is proved, the inner equilibria is local asymptotic stable as τ < τ0; the inner equilibria is unstable as τ = τ0, it appears a Hopf bifurcation in the system as τ > τ0.At last the numerical simulation is given with the Matlab software, and the rationality of the theoretical analysis is verified.关键词
