WebA codimension-three Takens–Bogdanov bifurcation in reversible systems has been very recently analyzed in the literature. In this paper, we study with the help of the nonlinear time transformation method, the codimension-one and -two homoclinic and heteroclinic connections present in the corresponding unfolding. 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.

WebWe classify the local bifurcations of quasi-periodic d-dimensional tori in maps (abbr. MTd) and in flows (abbr. FTd) for d ≥ 1. It is convenient to classify these bifurcations into normal bifurcations and resonance bifurcations. Normal bifurcations of MTd can be classified into four classes: namely, saddle-node, period doubling, double covering, and … Web12 de out. de 2024 · High Codimension Bifurcations of a Predator–Prey System with Generalized Holling Type III Functional Response and Allee Effects Alessandro Arsie, Chanaka Kottegoda & Chunhua Shan Journal of Dynamics and Differential Equations ( …

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.
