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

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 Solutions of Hamiltonian Systems with Symmetry [PDF]

open access: yesJournal of Differential Equations, 1999
Consider a Hamiltonian system with a Hamiltonian of the following form: \[ H(z,t)=\tfrac{1}{2}Az\cdot z+F(z,t). \] The authors show that if (i) the spectrum of the matrix \(JA\) (where \(J\) is the standard symplectic matrix) does not intersect the imaginary axis; (ii) \(F\) is invariant under the action of a compact Lie group; and (iii) \(F\) is ...

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.

Homoclinic Solutions of an Integral Equation: Existence and Stability [PDF]

open access: yesJournal of Differential Equations, 1999
The authors study (stationary) evolution equation in the form of the following nonlinear convolution type integral equation \[ (J\ast u)(x)- u(x)-f[u(x)]=0,\tag{1} \] with the condition \(u(\pm \infty)=0.\) It is assumed, that \(J(z)\geq 0\), \(\int J(z) dz =1\) and \(f\) is bistable. They construct homoclinic (even) solutions to the equation (1).

Homoclinic solutions for Hamiltonian system with impulsive effects

open access: yesAdvances in Difference Equations, 2018
In this article, we investigate a class of impulsive Hamiltonian systems with a p-Laplacian operator. By establishing a series of new sufficient conditions, the existence of homoclinic solutions to such type of systems is revealed.

Multiple bursting patterns in lateral habenula neurons: Experiments and computational model. [PDF]

open access: yesJ Physiol
Abstract figure legend LHb neurons display a variety of bursting patterns, as well as being silent or displaying a tonic or irregular firing pattern. In a set of patch‐clamp experiments in ex vivo mouse lateral habenula (LHb), we were able to record from a number of cells showing characteristic bursts of a few distinguishable types.

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
