同宿轨道的不变流形和超同宿轨道的动力学结果:具有(mathbb{Z}_2)-对称性和运动积分的(mathbb{R}^4)的例子研究

Invariant manifolds of homoclinic orbits and the dynamical consequences of a super-homoclinic: A case study in (mathbb{R}^4) with (mathbb{Z}_2)-symmetry and integral of motion

摘要:

本文考虑(mathbb{R}^{4})中的(mathbb{Z}_2)-等变流,它具有一个运动积分和一个具有横截同宿轨道(Gamma)的双曲平衡。给出了(Gamma)的稳定和不稳定不变流形存在的判据.我们证明了,如果这些流形相交横向,创建一个所谓的超同宿,那么在这个超同宿的任何邻域存在无限多个多脉冲同宿环。应用到耦合非线性薛定谔方程的系统被认为是。

英文摘要:

We consider a (mathbb{Z}_2)-equivariant flow in (mathbb{R}^{4}) with an integral of motion and a hyperbolic equilibrium with a transverse homoclinic orbit (Gamma). We provide criteria for the existence of stable and unstable invariant manifolds of (Gamma). We prove that if these manifolds intersect transversely, creating a so-called super-homoclinic, then in any neighborhood of this super-homoclinic there exist infinitely many multi-pulse homoclinic loops. An application to a system of coupled nonlinear Schrödinger equations is considered.
