Bifurcations and Chaos in an SIR Model with Nonlinear Incidence Rate
In this paper, bifurcations and chaos in an SIR model of epidemic dynamics with a periodically nonlinear incidence rate are studied. Firstly the equations are transformed into amenable to Melnikov analysis by a series of coordinate transformations. And then the existence of chaotic motion of the models is established mathematically by Melnikovs method. At last the numerical simulations are made for the conclusions.
