报告摘要:

The bifurcation of most epidemic models oncomplex networks leading from a  disease free equilibrium to an endemic equilibrium is forward. Gross et al.  established a pair-approximation epidemic model for the spreading of infections  on an adaptive network based on thewell-known SIS model, and numerical studies  have figured out that the rewiringmechanism can lead to backward bifurcation and  Hopf bifurcation. However, theyhave not presented a strict mathematical proof of  their conclusion in the literature. In this talk, we give the basic reproduction  number and thecritical conditions of the bifurcations occur analytically.  Furthermore, wegive a detailed analysis for these rich dynamical behaviors, such  asbistability and periodicity.
