六阶非定域逆时AKNS系统的Riemann-Hilbert问题及$N$ -孤子的动力学行为

Riemann-Hilbert problems of a non-local reverse-time AKNS system of six-order and dynamical behaviours of $N$-soliton

Ahmed M. G. Ahmed, Alle Adjiri

摘要:

本文研究非线性非局部逆时六分量六阶AKNS系统。我们使用逆时约化将耦合系统约化为一个可积的六阶NLS型方程。从AKNS系统的谱问题出发,将公式化Riemann-Hilbert问题。该公式允许通过使用位于矩阵Jost解决方案的内核中的向量来生成孤子解决方案。当反射系数为零时,跳跃矩阵是恒等的,相应的Riemann-Hilbert问题产生孤子解,从而探索它们的动力学。

英文摘要:

In this paper, we are going to solve nonlinear nonlocal reverse-time six-component six-order AKNS system. We used reverse-time reduction to reduce the coupled system to an integrable six-order NLS-type equation. Starting from the spectral problem of the AKNS system, a Riemann-Hilbert problem will be formulated. This formulation allows to generate soliton solutions by using the vectors lying in the kernel of the matrix Jost solutions. When reflection coefficients are zeros, the jump matrix is identity and the corresponding Riemann-Hilbert problem yields soliton solutions, leading to explore their dynamics.
