Transcritical and zero-Hopf bifurcations in the Genesio system [PDF]

open access: yesNonlinear Dynamics, 2016
Agraïments: The first author is supported by FAPESP Grant No. 2013/24541-0. Both authors are supported by CAPES Grant 88881.030454/2013-01 Program CSF-PVE. In this paper we study the existence of transcritical and zero--Hopf bifurcations of the third--order ordinary differential equation a b c x - x^2 = 0, called the Genesio equation, which has a ...

Bifurcations of Orbit and Inclination Flips Heteroclinic Loop with Nonhyperbolic Equilibria

open access: yesThe Scientific World Journal, 2014
The bifurcations of heteroclinic loop with one nonhyperbolic equilibrium and one hyperbolic saddle are considered, where the nonhyperbolic equilibrium is supposed to undergo a transcritical bifurcation; moreover, the heteroclinic loop has an orbit flip ...

Imperfect transcritical and pitchfork bifurcations

open access: yesJournal of Functional Analysis, 2007
Let \(X\) and \(Y\) be Banach spaces, \(F: \mathbb{R} \times X \to Y\) a nonlinear differentiable map. The authors study the bifurcations of solutions for the equation \[ F(\lambda, u) = 0 \] in a neighborhood of a point \((\lambda_0, u_0)\) under the following assumptions: (F1) \(\dim N\left(F_u\left(\lambda_0,u_0\right)\right) = \text{codim}\,R \left(

Discretizing the transcritical and pitchfork bifurcations – conjugacy results [PDF]

open access: yesJournal of Difference Equations and Applications, 2015
We present two case studies in one-dimensional dynamics concerning the discretization of transcritical (TC) and pitchfork (PF) bifurcations. In the vicinity of a TC or PF bifurcation point and under some natural assumptions on the one-step discretization method of order $p\ge 1$, we show that the time-$h$ exact and the step-size-$h$ discretized ...

Transcritical Bifurcations and Algebraic Aspects of Quadratic Multiparametric Families

open access: yesWSEAS TRANSACTIONS ON MATHEMATICS, 2021
This article reveals an analysis of the quadratic systems that hold multiparametric families therefore, in the first instance the quadratic systems are identified and classified in order to facilitate their study and then the stability of the critical points in the finite plane, its bifurcations, stable manifold and lastly, the stability of the ...

Bifurcation and Chaotic Behavior of a Discrete-Time SIS Model

open access: yesDiscrete Dynamics in Nature and Society, 2013
The discrete-time epidemic model is investigated, which is obtained using the Euler method. It is verified that there exist some dynamical behaviors in this model, such as transcritical bifurcation, flip bifurcation, Hopf bifurcation, and chaos.

Complicate dynamical properties of a discrete slow-fast predator-prey model with ratio-dependent functional response

open access: yesScientific Reports, 2023
Using a semidiscretization method, we derive in this paper a discrete slow-fast predator-prey system with ratio-dependent functional response. First of all, a detailed study for the local stability of fixed points of the system is obtained by invoking an

Stability and Bifurcation in a Predator–Prey Model with the Additive Allee Effect and the Fear Effect

open access: yesMathematics, 2020
We proposed and analyzed a predator–prey model with both the additive Allee effect and the fear effect in the prey. Firstly, we studied the existence and local stability of equilibria.

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 ...
