论文摘要
在（1+1） - 在无穷大的零边界条件下（零边界条件下）中的Heisenberg Ferromagnetic Spin链系统的广义不均匀的高阶非线性schrodinger（Gihnls）方程。首先进行光谱分析以在真实轴上产生相关的矩阵riemann-hilbert问题。然后，通过将跳跃矩阵作为身份矩阵来求解所得的矩阵riemann-hilbert问题，可以实现通用的亮度多 - 索尔顿溶液到Gihnls方程。此外，一单溶剂和两索溶液是通过数字编写和分析的。
A generalized inhomogeneous higher-order nonlinear Schrodinger (GIHNLS) equation for the Heisenberg ferromagnetic spin chain system in (1+1)-dimensions under zero boundary condition at infinity is taken into account. The spectral analysis is first performed to generate a related matrix Riemann-Hilbert problem on the real axis. Then, through solving the resulting matrix Riemann-Hilbert problem by taking the jump matrix to be the identity matrix, the general bright multi-soliton solutions to the GIHNLS equation are attained. Furthermore, the one- and two-soliton solutions are written out and analyzed by figures.
