Abstract：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 perturbation. The materials reported here contain the joint works with Xianfeng Chen and Wei Su.
