Homoclinic solutions for a class of second order non-autonomous systems

open access: yesElectronic Journal of Differential Equations, 2009
This article concerns the existence of homoclinic solutions for the second order non-autonomous system $$ ddot q+A dot q-L(t)q+W_{q}(t,q)=0, $$ where $A$ is a skew-symmetric constant matrix, $L(t)$ is a symmetric positive definite matrix depending ...

Rigorous numerics for symmetric homoclinic orbits in reversible dynamical systems [PDF]

open access: yes, 2007
summary:We propose a new rigorous numerical technique to prove the existence of symmetric homoclinic orbits in reversible dynamical systems. The essential idea is to calculate Melnikov functions by the exponential dichotomy and the rigorous numerics. The

Snake-to-isola transition and moving solitons via symmetry-breaking in discrete optical cavities [PDF]

open access: yes, 2010
This paper continues an investigation into a one-dimensional lattice equation that models the light field in a system comprised of a periodic array of pumped optical cavities with saturable nonlinearity.

Homoclinic Shadowing

open access: yes, 2005
A new method for rigorously establishing the existence of a transversal homoclinic orbit to a periodic orbit (or a fixed point) of diffeomorphisms in Rn is presented. It is a computer-assisted technique with two main components.

Homoclinic bifurcations in a planar dynamical system

open access: yes, 2022
S.1183-1191The homoclinic bifurcation properties of a planar dynamical system are analyzed and the corresponding bifurcation diagram is presented. The occurrence of two Bogdanov-Takens bifurcation points provides two local existing curves of homoclinic ...

Homoclinic-doubling cascades

open access: yes, 2001
Cascades of period-doubling bifurcation,; have attracted much interest from researchers of dynamical systems in the past two decades as they are one of the routes to onset of chaos.

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 ...

On Shilnikov's scenario in 3D: Topological chaos for vectorfields of class $C^1$

open access: yesElectronic Journal of Qualitative Theory of Differential Equations
Shilnikov's scenario in $\mathbb{R}^3$ means that the equation $x'=V(x)\in\mathbb{R}^3$ with $V(0)=0$ has a homoclinic solution and the eigenvalues of $DV(0)$ are $u>0$ and $\sigma\pm i\mu$ with ...

Homoclinic solutions of singular differential equations with $\phi$-Laplacian

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2018
A singular nonlinear initial value problem (IVP) with a $\phi$-Laplacian of the form $$ (p(t)\phi(u'(t)))'+ p(t)f(\phi(u(t)))=0, \quad u(0)=u_0 \in [L_0,0),\quad u'(0)=0 $$ is investigated on the half-line $[0,\infty)$.

Existence and multiplicity of homoclinic solutions for difference systems involving classical ( ϕ 1 , ϕ 2 ) $(\phi_{1},\phi_{2})$ -Laplacian and a parameter

open access: yesAdvances in Difference Equations, 2017
In this paper, we investigate the existence and multiplicity of homoclinic solutions for a class of nonlinear difference systems involving classical ( ϕ 1 , ϕ 2 ) $(\phi_{1},\phi _{2})$ -Laplacian and a parameter: { Δ ( ρ 1 ( n − 1 ) ϕ 1 ( Δ u 1 ( n − 1 )
