Hopf-zero bifurcation of Oregonator oscillator with delay

open access: yesAdvances in Difference Equations, 2018
In this paper, we study the Hopf-zero bifurcation of Oregonator oscillator with delay. The interaction coefficient and time delay are taken as two bifurcation parameters. Firstly, we get the normal form by performing a center manifold reduction and using

Analysis on recurrence behavior in oscillating networks of biologically relevant organic reactions

open access: yesMathematical Biosciences and Engineering, 2019
In this paper, we present a new method based on dynamical system theory to study certain type of slow-fast motions in dynamical systems, for which geometric singular perturbation theory may not be applicable.

Perturbed bifurcation theory

open access: yesJournal of Differential Equations, 1979
INTRODUCTION Imperfection-sensivity theory for structures has been the subject of many studies for some fifteen years [3][11][16]. I n mathematical terms, this theory leads to problems of perturbed bifurcation. In this respect, the British School [16][17] has studied systems with a finite number of degrees of freedom.

Analyzing Predator-Prey Interaction in Chaotic and Bifurcating Environments

open access: yesChaos Theory and Applications, 2023
An analysis of discrete-time predator-prey systems is presented in this paper by determining the minimum amount of prey consumed before predators reproduce, as well as by analyzing the system's stability and bifurcation. In order to investigate the local

Bifurcation Analysis and Spatiotemporal Patterns of Nonlinear Oscillations in a Ring Lattice of Identical Neurons with Delayed Coupling

open access: yesAbstract and Applied Analysis, 2014
We investigate the dynamics of a delayed neural network model consisting of n identical neurons. We first analyze stability of the zero solution and then study the effect of time delay on the dynamics of the system.

Imperfect Homoclinic Bifurcations [PDF]

open access: yes, 2001
Experimental observations of an almost symmetric electronic circuit show complicated sequences of bifurcations. These results are discussed in the light of a theory of imperfect global bifurcations. It is shown that much of the dynamics observed in the circuit can be understood by reference to imperfect homoclinic bifurcations without constructing an ...

Bifurcation and Multiplicity Results for Elliptic Problems with Subcritical Nonlinearity on the Boundary [PDF]

open access: yesarXiv, 2021
We consider an elliptic problem with nonlinear boundary condition involving nonlinearity with superlinear and subcritical growth at infinity and a bifurcation parameter as a factor. We use re-scaling method, degree theory and continuation theorem to prove that there exists a connected branch of positive solutions bifurcating from infinity when the ...

Computational algebra for bifurcation theory

open access: yesJournal of Symbolic Computation, 2005
AbstractWe provide algorithmic methods for the solution of the classification problem of bifurcations by vanishing and non-vanishing derivatives. These methods come from a generalization of standard bases for modules in local rings. We introduce the necessary theory of bifurcations, provide the algorithmic tools, and show the effectiveness of these ...

Discrete prey-predator model with fear effect and strong Allee effect

open access: yesXi'an Gongcheng Daxue xuebao, 2023
The rich dynamic properties of a discrete prey-predator model with fear effect and strong Allee effect are studied. The piecewise constant argument method of differential equation is used to discretize the system, and the existence of equilibrium point ...
