WebHopf bifurcation of codimension 2 were also found to happen. In this paper, we will elaborate on these aspects for system (1) with a= 0. The existence and their stability of equilibrium points are introduced in Section 2. Bifurcations, such as, the saddle-node bifurcation, the Hopf bifurcation and the Bogdanov-Takes bifurcation of codimension … WebBifurcation theory analyzes the bifurcations within the normal forms and investigates the similarity of the dynamics within systems having a given bifurcation type. The "gold standard" for similarity of systems used by the theory is topological equivalence. In some cases, bifurcation theory proves structural stability of a family.
