• TITLE: Oscillatory Behavior of a Network Epidemic SIS Model with Nonlinear Infectivity

  AUTHORS: Chunhua Feng, Carl S. Pettis

  KEYWORDS: Sepidemic SIS Network Model; Delay; Oscillation

  JOURNAL NAME: Applied Mathematics, Vol.5 No.1, January 16, 2014

  ABSTRACT: In this paper, an epidemic SIS model with nonlinear infectivity on heterogeneous networks and time delays is investigated. The oscillatory behavior of the solutions is studied. Two sufficient conditions are provided to guarantee the oscillatory behavior for the solutions. Some computer simulations are demonstrated.
