WebSep 28, 2007 · The global existence of multiple periodic solutions is established using a global Hopf bifurcation result given by Wu (1998 Trans. Am. Math. Soc. 350 4799) and a Bendixson criterion for higher dimensional ordinary differential equations given by Li and Muldowney (1993 J. Diff. Eqns 106 27).

WebThe mathematical structure of a simple climate model is investigated. The model is governed by a system of two nonlinear, autonomous differential equations for the evolution in time of global temperature T and meridional ice-sheet extent L. The system’s solutions are studied by a combination of qualitative reasoning with explicit calculations, both … Web5. Global Continuation of the Local Hopf Bifurcation. In this section, we will study the global continuation of periodic solutions bifurcating from the point for is fixed in the interval .Further, the method we used here is based on the global Hopf bifurcating theorem for general functional differential equations introduced by Wu [].For convenience, we denote … townhouse queens

WebMar 24, 2024 · Thirdly, bifurcation analysis at these equilibria is investigated, and it is found that the system undergoes a sequence of bifurcations, including Hopf, degenerate Hopf bifurcation, homoclinic bifurcation, the cusp type Bogdanov–Takens bifurcation of codimension 2, and the focus type Bogdanov–Takens bifurcation of codimension 3 … WebMay 25, 2024 · Especially, we examine the onset and termination of Hopf bifurcations of periodic solutions from the unique positive equilibrium. We locate all of the stability switches for the equilibrium and demonstrate that the global Hopf bifurcation branches are bounded. This result implies the system undergoes oscillatory behavior only with … WebWe show that the dynamics on this manifoid is a perturbation of the well-known center of the Lotka-Volterra model. Finally, we prove that a weak change of behavior can lead to a subcritical Hopf bifurcation in the global dynamics.
