Abstract

In this paper we discuss an improved Riemann–Hilbert method, by which arbitrary higher-order soliton solutions for the derivative nonlinear Schrödinger equation can be directly obtained. The explicit determinant form of a higher-order soliton which corresponds to one pth order pole is given. Besides the interaction related to one simple pole and the other one double pole is considered.

通过改进的黎曼-希尔伯特方法求得衍生非线性薛定谔方程的高阶孤子解

本文讨论了一种改进的黎曼-希尔伯特方法，通过这种方法可以直接得到导数非线性薛定谔方程的任意高阶孤子解。本文给出了与一个 pth 阶极点相对应的高阶孤子的显式行列式。此外，还考虑了与一个简单极点和另一个双极点相关的相互作用。
