Global dynamics of an SI epidemic model with nonlinear incidence rate, feedback controls and time delays

  • Received: 16 August 2020 Accepted: 01 December 2020 Published: 15 December 2020
  • In this paper, we consider a class of SI epidemic model with nonlinear incidence, feedback controls and four different discrete time delays. By skillfully constructing appropriate Lyapunov functionals, and combining Lyapunov-LaSalle invariance principle and Barbalat's lemma, the global dynamics of the model are established. Our results extend and improve related works in the existing literatures.
