Periodic orbits for an autonomous version of the Duffing–Holmes oscillator

open access: yesNonlinear Analysis
In the autonomous Duffing–Holmes oscillator, the existence of periodic orbits was detected numerically. Using the Hopf bifurcation theory, we prove analytically that such periodic orbits exist.

Stability and Hopf bifurcation periodic orbits in delay coupled Lotka-Volterra ring system

open access: yesOpen Mathematics, 2019
In this paper, we consider a class of delay coupled Lotka-Volterra ring systems. Based on the symmetric bifurcation theory of delay differential equations and representation theory of standard dihedral groups, properties of phase locked periodic ...

Bifurcation Analysis of a Class of Two-Delay Lotka–Volterra Predation Models with Coefficient-Dependent Delay

open access: yesMathematics
In this paper, a class of two-delay differential equations with coefficient-dependent delay is studied. The distribution of the roots of the eigenequation is discussed, and conditions for the stability of the internal equilibrium and the existence of ...

Global stability and bifurcation analysis of a delayed predator-prey system with prey immigration

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2016
A delayed predator-prey system with a constant rate immigration is considered. Local and global stability of the equilibria are studied, a fixed point bifurcation appears near the boundary equilibrium and Hopf bifurcation occurs near the positive ...

On the bifurcation of periodic orbits [PDF]

open access: yesarXiv, 2001
This article is a survey on recent contributions to an effective version of Bautin's theory about the bifurcation of periodic orbits (limit cycles). The analysis of Hopf bifurcations of higher order is possible by use of the return mapping. Explicit estimates of the size of the domain on which the number of limit cycles is controlled are important in ...

Bifurcation Analysis in Population Genetics Model with Partial Selfing

open access: yesAbstract and Applied Analysis, 2013
A new model which allows both the effect of partial selfing selection and an exponential function of the expected payoff is considered. This combines ideas from genetics and evolutionary game theory.

Numerical bifurcation and hybrid control of a Gompertz model with time delay

open access: yesJournal of Hebei University of Science and Technology, 2019
In order to study the stability of species, the biological systems are required to reduce or expand the stable region. For a Gompertz model with time delay, a hybrid control Euler method is proposed in which state feedback and parameter perturbation are ...

Coexistence of steady state for a diffusive prey-predator model with harvesting

open access: yesElectronic Journal of Differential Equations, 2016
In this article, we study a diffusive prey-predator model with modified Leslie-Gower term and Michaelis-Menten type prey harvesting, subject to homogeneous Dirichlet boundary conditions.
