摘要
借助谱问题的规范变换,给出与一个离散的2×2矩阵谱问题相联系的耦合离散mKdV方程的达布变换.作为应用,从所导出的达布变换得到了这个方程的精确解并作出了图形.
With the help of a gauge transformation of the spectral problem,gave the Darboux transformation of a discrete coupled mKdV equation,which related to the discrete 2×2 matrix spectral problem.As an application,obtained the explicit solutions of the discrete coupled mKdV equation by the formerly constructed Darboux transformation and their graph.
