Resonant Homoclinic Flips Bifurcation in Principal Eigendirections

open access: yesAbstract and Applied Analysis, 2013
A codimension-4 homoclinic bifurcation with one orbit flip and one inclination flip at principal eigenvalue direction resonance is considered. By introducing a local active coordinate system in some small neighborhood of homoclinic orbit, we get the ...

Bifurcation and chaos for piecewise nonlinear roll system of rolling mill

open access: yesAdvances in Mechanical Engineering, 2017
A non-smooth cold roll system of rolling mill is studied to reveal the bifurcation of the piecewise-smooth and discontinuous system. To examine the influence of the parameters on the dynamics, the bifurcation diagram is constructed when it is unperturbed.

Relaxation oscillations of a piecewise-smooth slow-fast Bazykin's model with Holling type Ⅰ functional response

open access: yesMathematical Biosciences and Engineering, 2023
In this paper, we consider the dynamics of a slow-fast Bazykin's model with piecewise-smooth Holling type Ⅰ functional response. We show that the model has Saddle-node bifurcation and Boundary equilibrium bifurcation.

Symmetry breaking perturbations and strange attractors [PDF]

open access: yes, 1996
The asymmetrically forced, damped Duffing oscillator is introduced as a prototype model for analyzing the homoclinic tangle of symmetric dissipative systems with \textit{symmetry breaking} disturbances.

Bifurcation of homoclinics [PDF]

open access: yesProceedings of the American Mathematical Society, 2007
We show that homoclinic trajectories of nonautonomous vector fields parametrized by a circle bifurcate from the stationary solution when the asymptotic stable bundles of the linearization at plus and minus infinity are “twisted” in different ways.

The Twisting Bifurcations of Double Homoclinic Loops with Resonant Eigenvalues

open access: yesAbstract and Applied Analysis, 2013
The twisting bifurcations of double homoclinic loops with resonant eigenvalues are investigated in four-dimensional systems. The coexistence or noncoexistence of large 1-homoclinic orbit and large 1-periodic orbit near double homoclinic loops is given ...

Quantum dynamics in a cubic potential in the semi-classical limit: Smearing of the homoclinic bifurcation

open access: yesPhysics Open, 2021
We consider the dynamics of a particle inside the metastable well of a cubic potential. In the classical picture the particle can oscillate inside the well when its total energy is less than a critical value Ec at which point a homoclinic bifurcation ...

Complex Behaviors of Epidemic Model with Nonlinear Rewiring Rate

open access: yesComplexity, 2020
An SIS propagation model with the nonlinear rewiring rate on an adaptive network is considered. It is found by bifurcation analysis that the model has the complex behaviors which include the transcritical bifurcation, saddle-node bifurcation, Hopf ...

Bifurcation and Chaos Prediction in Nonlinear Gear Systems

open access: yesShock and Vibration, 2014
The homoclinic bifurcation and transition to chaos in gear systems are studied both analytically and numerically. Applying Melnikov analytical method, the threshold values for the occurrence of chaotic motion are obtained.
