在KdV的背景下,我们重温经典的达布变换的向量黎曼-希尔伯特问题的框架。这很容易产生一个版本的二元达布变换,为孤子在广泛的背景解上的传播提供了显式公式的捷径。我们的方法还链接到二进制达布变换和双交换方法。
In the KdV context, we revisit the classical Darboux transformation in the framework of the vector Riemann–Hilbert problem. This readily yields a version of the binary Darboux transformation providing a short‐cut to explicit formulas for solitons traveling on a wide range of background solutions. Our approach also links the binary Darboux transformation and the double commutation method.
