Global stability analysis for delayed virus infection model with general incidence rate and humoral immunity

Wang, Tianlei; Hu, Zhixing; Liao, Fucheng; Ma, Wanbiao - In: Mathematics and Computers in Simulation (MATCOM) 89 (2013) C, pp. 13-22

In this paper, we investigate the dynamical behavior of a virus infection model with general incidence rate and humoral immunity. By using suitable Lyapunov functional and the LaSalle's invariance principle, we establish the global stability of the three equilibria. The uninfected equilibrium E0...
