耦合波粒方程中孤子的散射

Scattering of Solitons for Coupled Wave-Particle Equations

Valery Imaykin, Alexander Komech, Boris Vainberg

摘要:

建立了一个与带电粒子耦合的非线性波动方程系统的长时间孤子渐近性。耦合系统有一个六维流形的孤子解。我们证明了在大时间近似下,任何初始状态接近孤立子流形的解都是孤立子和色散波的和,色散波是自由波方程的解。假设电荷密度满足费密黄金法则的维纳条件,且电荷分布的动量在四阶以下为零。证明是基于发展的一般战略介绍了Buslaev和Perelman:辛投影在希尔伯特空间上的孤流形,调制方程的参数的投影,和衰减的横向分量。

英文摘要:

We establish a long time soliton asymptotics for a nonlinear system of wave equation coupled to a charged particle. The coupled system has a six dimensional manifold of soliton solutions. We show that in the large time approximation, any solution, with an initial state close to the solitary manifold, is a sum of a soliton and a dispersive wave which is a solution to the free wave equation. It is assumed that the charge density satisfies Wiener condition which is a version of Fermi Golden Rule, and that the momenta of the charge distribution vanish up to the fourth order. The proof is based on a development of the general strategy introduced by Buslaev and Perelman: symplectic projection in Hilbert space onto the solitary manifold, modulation equations for the parameters of the projection, and decay of the transversal component.
