>       Mathematical Analysis of the Global Dynamics of a Model
        for HIV Infection of CD4+ T cells

> Abstract. A mathematical model that describes the interaction of HIV
> infection and CD4$^+$T cells is studied. Global dynamics analysis is
> rigorously established. After identifying a basic reproduction number
> R0, we establish that, if $R_0\le 1,$ the HIV infection dies out; if
> $R_0 > 1,$ the HIV infection persists, solutions approach either the
> unique endemically infected steady state or periodic orbits.
>
The presentation will be of special interest for faculty and students in
Mathematics and Biological Science.
