نویسنده
چکیده
We describe and characterize rigorously the homoclinic structure of the perturbed sine{ Gordon equation under periodic boundary conditions. The existence of invariant manifolds for a perturbed sine{Gordon equation is established. Mel'nikov method, together with geometric analysis are used to assess the persistence of the homoclinic orbits under bounded and time-periodic perturbations.

Homoclinic Orbits in Near-Integrable Double Discrete sine-Gordon Equation
We establish the existence of homoclinic orbits for the near{integrable double discrete sine-Gordon (dDSG) equation under periodic boundary conditions. The hyperbolic structure and homoclinic orbits are constructed through the B acklund transformation and Lax pair. A geometric perturbation method based on Mel'nikov analysis is used to establish necessary criteria for the persistent of temporal...

We describe and characterize rigorously the chaotic behavior of the sine– Gordon equation. The existence of invariant manifolds and the persistence of homoclinic orbits for a perturbed sine–Gordon equation are established. We apply a geometric method based on Mel’nikov’s analysis to derive conditions for the transversal intersection of invariant manifolds of a hyperbolic point of the perturbed ...
متن کاملHomoclinic tubes and chaos in perturbed sine-Gordon equation
Sine-Gordon equation under a quasi-periodic perturbation or a chaotic perturbation is studied. Existence of a homoclinic tube is proved. Established are chaos associated with the homoclinic tube, and ‘‘chaos cascade’’ referring to the embeddings of smaller scale chaos in larger scale chaos. 2003 Elsevier Ltd. All rights reserved.
متن کاملPersistence of Homoclinic Orbits in a Discretized NLS Equation with Hamiltonian Perturbation
We study the dynamics of a Discretized NLS (DNLS) equation with Hamiltonian perturbation on the periodic domain. The unperturbed system consists of a inte-grable DNLS equation for which the corresponding Lax pair is known. We prove the persistence of homoclinic orbits for this system and derive a formula for the distance between the invariant manifolds of a torus of unstable equilibria for a cl...
متن کاملMel'nikov Analysis of a Hamiltonian Perturbation of the Nonlinear Schr Odinger Equation
Homoclinic varieties play a crucial role in the dynamics of perturbations of the focusing Nonlinear Schrr odinger equation (NLS). We undertake a Mel'nikov analysis to investigate the possibility of persistence of transversal homoclinic orbits for a conservative perturbation of the NLS.
