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.
