Stability and Hopf bifurcation for a stage-structured predator–prey model incorporating refuge for prey and additional food for predator

open access: yesAdvances in Differential Equations, 2019
In this paper, we study a stage-structured predator–prey model incorporating refuge for prey and additional food for predator. By analyzing the corresponding characteristic equations, we investigate the local stability of equilibria and the existence of ...

Hopf Bifurcation and Chaos of a Delayed Finance System

open access: yesComplex, 2019
In this paper, a finance system with delay is considered. By analyzing the corresponding characteristic equations, the local stability of equilibrium is established. The existence of Hopf bifurcations at the equilibrium is also discussed.

Bifurcation Analysis of the Watt Governor System [PDF]

open access: yes, 2006
This paper pursues the study carried out by the authors in {\it Stability and Hopf bifurcation in the Watt governor system} \cite{smb}, focusing on the codimension one Hopf bifurcations in the centrifugal Watt governor differential system, as presented ...

Oscillations and secondary bifurcations in nonlinear magnetoconvection [PDF]

open access: yes, 1993
Complicated bifurcation structures that appear in nonlinear systems governed by partial differential equations (PDEs) can be explained by studying appropriate low-order amplitude equations.

Hopf bifurcation and steady-state bifurcation for a Leslie-Gower prey-predator model with strong Allee effect in prey

open access: yesDiscrete and Continuous Dynamical Systems. Series A, 2019
It is well known that the Leslie-Gower prey-predator model (without Allee effect) has a unique globally asymptotically stable positive equilibrium point, thus there is no Hopf bifurcation branching from positive equilibrium point.

Stability and Hopf Bifurcation Analysis of a Vector-Borne Disease with Time Delay

open access: yesJournal of Applied Mathematics, 2014
A delay-differential modelling of vector-borne is investigated. Its dynamics are studied in terms of local analysis and Hopf bifurcation theory, and its linear stability and Hopf bifurcation are demonstrated by studying the characteristic equation.

Hopf bifurcation of a heroin model with time delay and saturated treatment function

open access: yesAdvances in Differential Equations, 2019
In this paper, local stability and Hopf bifurcation of a delayed heroin model with saturated treatment function are discussed. First of all, sufficient conditions for local stability and existence of Hopf bifurcation are obtained by regarding the time ...

On the nonautonomous Hopf bifurcation problem [PDF]

open access: yesDiscrete & Continuous Dynamical Systems - S, 2016
Under well-known conditions, a one-parameter family of two-dimensional, autonomous ordinary differential equations admits a supercritical\break Andronov-Hopf bifurcation. Let such a family be perturbed by a non-autonomous term. We analyze the sense in which and some conditions under which the Andronov-Hopf pattern persists under such a perturbation.

Bursting Oscillations in General Coupled Systems: A Review

open access: yesMathematics, 2023
In this paper, the bursting oscillation phenomenon in coupled systems with two time scales is introduced. Firstly, several types of bifurcation are briefly introduced: fold bifurcation, Hopf bifurcation, fold limit cycle bifurcation, homoclinic ...

Bifurcation analysis of a normal form for excitable media: Are stable dynamical alternans on a ring possible?

open access: yes, 2008
We present a bifurcation analysis of a normal form for travelling waves in one-dimensional excitable media. The normal form which has been recently proposed on phenomenological grounds is given in form of a differential delay equation.
