A class of delayed virus dynamics models with multiple target cells

Two delayed virus dynamics models with multi-target cells and bilinear incidence rate or general incidence rate are studied in this paper. The delays correspond to be the time needed for a newly infected cell to start producing viruses and the time needed for a newly produced virus to become infectious, respectively. Our models include \documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$n$$\end{document} uninfected target cells, \documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$n$$\end{document} infected target cells and the virus particles. By constructing Lyapunov functionals, we establish the global asymptotic stabilities of the infection-free equilibria and positive equilibria of these models.
