We take a closer look at the Riemann-Hilbert problem associated to one-gap solutions of the Korteweg-de Vries equation. To gain more insight, we reformulate it as a scalar Riemann-Hilbert problem on the torus. This enables us to derive deductively the model vector-valued and singular matrix-valued solutions in terms of Jacobi theta functions. We compare our results with those obtained in recent literature.
我们更深入地研究与Korteweg-de Vries方程的单间隙解相关的黎曼-希尔伯特问题。为了获得更多见解，我们将其重新表述为环面上的标量黎曼-希尔伯特问题。这使我们能够根据雅可比θ函数演绎地推导出模型向量值和奇异矩阵值解。我们将我们的结果与最近文献中获得的结果进行比较。
