摘要

本文以[Appl. Math. Lett. 158 (2024) 109217]中探索的框架为基础，提出了一个扩展的半离散矩阵耦合无色散系统。我们提出了一个拉克斯对，并利用达尔布克斯变换构建了显式解。这些解揭示了各种现象，包括周期模式、呼吸波和流氓波。值得注意的是，扩展系统在亮孤子和暗孤子之间以及亮孤子和流氓波之间表现出错综复杂的相互作用。此外，我们还提供了还原半离散耦合无分散方程的数值实验，以证明所开发方法的有效性。

On an extended semi-discrete matrix coupled dispersionless system: Darboux transformation and explicit solutions

In this paper, we present an extended semi-discrete matrix coupled dispersionless system, building on the framework explored in [Appl. Math. Lett. 158 (2024) 109217]. We propose a Lax pair and employ the Darboux transformation to construct explicit solutions. These solutions reveal diverse phenomena, including periodic patterns, breathers, and rogue waves. Notably, the extended system exhibits intricate interactions between bright and dark solitons and between bright solitons and rogue waves. Furthermore, we provide a numerical experiment for the reduced semi-discrete coupled dispersionless equations to demonstrate the effectiveness of the developed method.
