Existence problems for homoclinic solutions

open access: yesAbstract and Applied Analysis, 2002
The problem x˙=f(t,x), x(−∞)=x(+∞), where x(±∞):=limt→±∞x(t)∈ℝn, is considered. Some existence results for this problem are established using the fixed point method and topological degree theory.

Existence and multiplicity of homoclinic solutions for a difference equation

open access: yesElectronic Journal of Differential Equations, 2020
The aim of this article is to obtain homoclinic solutions for a discrete problem involving p-Laplacian. We prove the existence of at least one, two and three solutions for the problem. Our approach is based on variational methods.

Homoclinic and quasi-homoclinic solutions for damped differential equations

open access: yesElectronic Journal of Differential Equations, 2015
We study the existence and multiplicity of homoclinic solutions for the second-order damped differential equation $$ \ddot{u}+c\dot{u}-L(t)u+W_u(t,u)=0, $$ where L(t) and W(t,u) are neither autonomous nor periodic in t. Under certain assumptions on

Bifurcation of big periodic orbits through symmetric homoclinics‎, ‎application to Duffing equation [PDF]

open access: yesJournal of Mahani Mathematical Research, 2023
‎We consider a planar symmetric vector field that undergoes a homoclinic bifurcation‎. ‎In order to study the existence of exterior periodic solutions of the vector field around broken symmetric homoclinic orbits‎, ‎we investigate the existence of fixed ...

Global Continuation of Homoclinic Solutions [PDF]

open access: yesZeitschrift für Analysis und ihre Anwendungen, 2018
When extending bifurcation theory of dynamical systems to nonautonomous problems, it is a central observation that hyperbolic equilibria persist as bounded entire solutions under small temporally varying perturbations. In this paper, we abandon the smallness assumption and aim to investigate the global structure of the entity of all such bounded entire

Role of Homoclinic Breathers in the Interpretation of Experimental Measurements, With Emphasis on the Peregrine Breather

open access: yesFrontiers in Physics, 2022
A class of generalized homoclinic solutions of the nonlinear Schrödinger (NLS) equation in 1+1 dimensions is studied. These are homoclinic breathers that are shown to be derivable from the ratio of Riemann theta functions for the genus-2 solutions of ...
