Dynamics of predator-prey models with Sigmoid functional response
主讲人:张祥
摘要:This talk introduces our results on the global dynamics of the predator-prey models with Sigmoid functional response. The main results are on global stability of the positive equilibrium, sub-and supercritical Hopf bifurcation, relaxation oscillation, canard explosion, homoclinic and heteroclinic connections and so on. The main tools are qualitative and bifurcation theories via singular perturcation.
