摘要: In this talk, we propose a mathematical model for HIV infection with delays in cell infection and virus production.  The model examines a viral-therapy for controlling infections through recombining HIV virus with a genetically modified virus. For this model, we derive two biologically insightful quantities (reproduction numbers) $\\mathcal{R}_0$ and $\\mathcal{R}_z$, and their threshold properties are discussed. When $\\mathcal{R}_0 1$ and $\\mathcal{R}_z<1 $, the single-infection equilibrium $e_s$ is globally asymptotically stable. when $\\mathcal{r}_z>1$, there occurs the double-infection equilibrium $E_d$, and there exists a constant $R_b$ such that $E_d$ is asymptotically stable if $1
