Unfoldings of Singular Hopf Bifurcation [PDF]

open access: yesSIAM Journal on Applied Dynamical Systems, 2012
Singular Hopf bifurcation occurs in generic families of vector-fields with two slow variables and one fast variable. Normal forms for this bifurcation depend upon several parameters, and the dynamics displayed by the normal forms is intricate. This paper analyzes a normal form for this bifurcation.

Hopf Bifurcation Control in a Delayed Predator-Prey System with Prey Infection and Modified Leslie-Gower Scheme

open access: yesAbstract and Applied Analysis, 2013
Hopf bifurcation of a delayed predator-prey system with prey infection and the modified Leslie-Gower scheme is investigated. The conditions for the stability and existence of Hopf bifurcation of the system are obtained.

Controlling hopf bifurcations: Discrete-time systems

open access: yesDiscrete Dynamics in Nature and Society, 2000
Bifurcation control has attracted increasing attention in recent years. A simple and unified state-feedback methodology is developed in this paper for Hopf bifurcation control for discrete-time systems. The control task can be either shifting an existing

Bifurcation Analysis and Sliding Mode Control of Chaotic Vibrations in an Autonomous System

open access: yesJournal of Applied Mathematics, 2014
We study the bifurcations and sliding mode control of chaotic vibrations in an autonomous system. More precisely, a Hopf bifurcation controller is designed so as to control the unstable subcritical Hopf bifurcation to the stable supercritical Hopf ...

Influence of Time Delay on Bifurcation in Fractional Order BAM Neural Networks With Four Delays

open access: yesIEEE Access, 2019
Over the past several decades, numerous scholars have studied the stability and Hopf bifurcation problem of integer-order delayed neural networks. However, the fruits about the stability and Hopf bifurcation for fractional-order delayed neural networks ...

Turing–Hopf bifurcation of a ratio-dependent predator-prey model with diffusion

open access: yesAdvances in Difference Equations, 2019
In this paper, the Turing–Hopf bifurcation of a ratio-dependent predator-prey model with diffusion and Neumann boundary condition is considered. Firstly, we present a kind of double parameters selection method, which can be used to analyze the Turing ...

Hopf Bifurcation Analysis of the Halvorsen System

open access: yesZanco Journal of Pure and Applied Sciences
This paper investigates local bifurcations in the Halvorsen system, focusing specifically on transcritical and Hopf bifurcations. The behavior of equilibrium points during bifurcations is studied using Sotomayor's theorem for transcritical bifurcation ...
