Based on the zero curvature equation as well as recursive operators, a new spectral problem and the associated multi-component Gerdjikov–Ivanov (GI) integrable hierarchy are studied. The bi-Hamiltonian structure of the multi-component GI hierarchy is obtained by the trace identity which shows that the multi-component GI hierarchy is integrable. In order to solve the multi-component GI system, a class of Riemann–Hilbert (RH) problem is constructed with the zero boundary. When the jump matrix is an identity matrix, the -soliton solutions of the integrable system are explicitly gained. At last, the one-, two- and -soliton solutions are explicitly shown.

零边界条件下的多分量Gerdjikov-Ivanov系统及其Riemann-Hilbert问题
基于零曲率方程以及递归算子,研究了一个新的光谱问题以及相关的多分量Gerdjikov-Ivanov(GI)可积层次。通过跟踪标识获得了多组分GI层次结构的双哈密顿结构,表明痕迹多组分GI层次结构是可集成的。为了解决多分量GI系统,构造了一类零边界的Riemann-Hilbert(RH)问题。当跳矩阵 是一个单位矩阵, 明确获得了可积系统的孤子解。最后,一,二和-soliton解决方案已明确显示。
