摘要
In this paper, we propose a discrete virus dynamics model with Holling type-II infection function. By constructing Lyapunov function, we prove that if R01, then the infection-free equilibrium is globally asymptotically stable; whereas if R0>1, then sufficient conditions are established for global stability of the infection equilibrium. Our results generalize some known results studied by other researchers. Copyright (c) 2015 John Wiley & Sons, Ltd.
