摘要

柯西矩阵法是在可积系统的研究中得到广泛应用的一种直接方法。在本文中，我们展示了Korteweg-de Vries层次结构及其解如何在柯西矩阵方法中表述。这样的公式可以推广到其他可积方程，承认柯西矩阵结构。

The KdV hierarchy: Cauchy matrix approach

The Cauchy matrix approach is a direct method that has been widely used in the study of integrable systems. In this paper, we show how the Korteweg–de Vries hierarchy and their solutions can be formulated in the Cauchy matrix approach. Such a formulation can be extended to other integrable equations that admit Cauchy matrix structure.
