Homoclinic orbits to invariant tori near a homoclinic orbit to center–center–saddle equilibrium [PDF]

open access: yesPhysica D: Nonlinear Phenomena, 2005
We consider a perturbation of an integrable Hamiltonian vector field with three degrees of freedom with a center–center–saddle equilibrium having a homoclinic orbit or loop. With the help of a Poincaré map (chosen based on the unperturbed homoclinic loop), we study the homoclinic intersections between the stable and unstable manifolds associated to ...

Chaotic motion around a black hole under minimal length effects

open access: yesEuropean Physical Journal C: Particles and Fields, 2020
We use the Melnikov method to identify chaotic behavior in geodesic motion perturbed by the minimal length effects around a Schwarzschild black hole. Unlike the integrable unperturbed geodesic motion, our results show that the perturbed homoclinic orbit,

Bifurcations of a Homoclinic Orbit to Saddle-Center in Reversible Systems

open access: yesAbstract and Applied Analysis, 2012
The bifurcations near a primary homoclinic orbit to a saddle-center are investigated in a 4-dimensional reversible system. By establishing a new kind of local moving frame along the primary homoclinic orbit and using the Melnikov functions, the existence

Bifurcation of Nongeneric Homoclinic Orbit Accompanied by Pitchfork Bifurcation

open access: yesAbstract and Applied Analysis, 2014
The bifurcation of a nongeneric homoclinic orbit (i.e., the orbit comes from the equilibrium along the unstable manifold instead of the center manifold) connecting a nonhyperbolic equilibrium is investigated, and the nonhyperbolic equilibrium undergoes ...

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 ...

Kuramoto Phase Model with Inertia: Bifurcations Leading to the Loss of Synchrony and to the Emergence of Chaos

open access: yesМоделирование и анализ информационных систем, 2015
We consider a finite-dimensional model of phase oscillators with inertia in the case of star configuration of coupling. The system of equations is reduced to a nonlinearly coupled system of pendulum equations.

Constructing the Second Order Poincaré Map Based on the Hopf-Zero Unfolding Method

open access: yesAbstract and Applied Analysis, 2013
We investigate the Shilnikov sense homoclinicity in a 3D system and consider the dynamical behaviors in vicinity of the principal homoclinic orbit emerging from a third order simplified system.

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 ...

On the Melnikov function [PDF]

open access: yesریاضی و جامعه, 2023
In this article, we have tried to introduce one of the most important topics in the subject of dynamical systems, namely the Melnikov function, in simple language.
