Existence and Uniqueness of Homoclinic Solution for a Class of Nonlinear Second-Order Differential Equations

open access: yesJournal of Applied Mathematics, 2012
The authors study the existence and uniqueness of a set with 2kT-periodic solutions for a class of second-order differential equations by using Mawhin's continuation theorem and some analysis methods, and then a unique homoclinic orbit is obtained as a ...

Homoclinic solutions for second order Hamiltonian systems with general potentials near the origin

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2013
In this paper, we study the existence of infinitely many homoclinic solutions for a class of second order Hamiltonian systems with general potentials near the origin. Recent results from the literature are generalized and significantly improved.

Infinitely Many Homoclinic Solutions for Nonperiodic Fourth Order Differential Equations with General Potentials

open access: yesAbstract and Applied Analysis, 2014
We investigate a class of nonperiodic fourth order differential equations with general potentials. By using variational methods and genus properties in critical point theory, we obtain that such equations possess infinitely homoclinic solutions.

Saddle-node bifurcations of multiple homoclinic solutions in ODES

open access: yesDiscrete and Continuous Dynamical Systems - B, 2017
The authors study periodic perturbations of differential equations possessing a homoclinic orbit along which the tangent spaces of the corresponding stable and unstable manifolds intersect in a three-dimensional space. This paper can be seen as a continuation of the work ``Multiple transverse homoclinic solutions near a degenerate homoclinic orbit ...

Multiple homoclinic solutions for a class of nonhomogeneous Hamiltonian systems

open access: yesBoundary Value Problems, 2018
By introducing a new superquadratic condition, we obtain the existence of two nontrivial homoclinic solutions for a class of perturbed second order Hamiltonian systems which are obtained by the mountain pass theorem and Ekeland’s variational principle.

Existence and uniqueness of positive even homoclinic solutions for second order differential equations

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2019
This paper is concerned with the existence of positive even homoclinic solutions for the $p$-Laplacian equation \begin{equation*} (|u'|^{p-2}u')' - a(t)|u|^{p-2}u+f(t,u)=0,\qquad t\in \mathbb{R}, \end{equation*} where $p\ge 2$ and the functions $a ...

Symmetric homoclinic solutions to the periodic orbits in the Michelson system

open access: yes, 2006
The Michelson system [D. Michelson, Steady solutions of the Kuramoto–Sivashinsky equation , Physica D 19 (1986), 89–111] $x'''+x'+0.5x^2=c^2$ for the parameter value $c=1$ is investigated. It was proven in \cite{8} that the system possesses two odd

Nonexistence of Homoclinic Solutions for a Class of Discrete Hamiltonian Systems [PDF]

open access: yesAbstract and Applied Analysis, 2013
We give several sufficient conditions under which the first-order nonlinear discrete Hamiltonian systemΔx(n)=α(n)x(n+1)+β(n)|y(n)|μ-2y(n),Δy(n)=-γ(n)|x(n+1)|ν-2x(n+1)-α(n)y(n)has no solution(x(n),y(n))satisfying condition0<∑n=-∞+∞[|x(n)|ν+(1+β(n))|y(n)|μ]<+∞, whereμ,ν>1and1/μ+1/ν=1andα(n),β(n),andγ(n)are real-valued functions defined onℤ.

Center manifolds for homoclinic solutions

open access: yes, 1995
In this article, center-manifold theory for homoclinic solutions of ordinary differential equations or semilinear parabolic equations is developed. Here, a center manifold along a homoclinic orbit q(t) is a locally invariant manifold containing all ...

Existence and stability of multiple spot solutions for the gray-scott model in R^2 [PDF]

open access: yes, 2005
We study the Gray-Scott model in a bounded two dimensional domain and establish the existence and stability of {\bf symmetric} and {\bf asymmetric} multiple spotty patterns. The Green's function and its derivatives together with two nonlocal eigenvalue
