摘 要：In this talk, we would like to establish a KAM-theorem for ordinary differential equations of finitely differentiable vector fields with multiple degeneracies. The theorem can be used to deal with the persistence of quasi-periodic invariant tori in multiple Hopf bifurcations and zero-multiple Hopf bifurcations, as well as the associated subordinate bifurcations, of equilibrium points of continuous systems.
