Dynamics of an Epidemic Model with Saturation Recovery and Delays
Authors: ,
Abstract: This paper discusses the dynamical behaviors of an SIRS epidemic model with saturation recovery and two delays. The main results are given in terms of local stability and Hopf bifurcation. By choosing the diverse delay as a bifurcation parameter, we show that the complex Hopf bifurcation phenomenon at the positive equilibrium of the model can occur as the diverse delay crosses the corresponding critical value. Particularly, the direction and stability of the local Hopf bifurcation are determined by using the normal form theory and center manifold theorem. Finally, some numerical simulations supporting our theoretical results are presented.
