摘要

为求解非等谱卡多姆采夫-彼得维亚什维利方程和非等谱修正卡多姆采夫-彼得维亚什维利方程开发了考奇矩阵方法。通过西尔维斯特方程(\(\boldsymbol{L})\boldsymbol{M}- \oldsymbol{M}\boldsymbol{K} = \boldsymbol{r}\),一组标量主函数 \(\{S^{(i,j)}\}) 被定义。我们利用非等谱分散关系推导出标量函数的演化过程。图中给出了一些显式解,并对其进行了动力学分析。

Nonisospectral Kadomtsev–Petviashvili equations from the Cauchy matrix approach

The Cauchy matrix approach is developed for solving nonisospectral Kadomtsev–Petviashvili equation and the nonisospectral modified Kadomtsev–Petviashvili equation. By means of a Sylvester equation \( \boldsymbol{L} \boldsymbol{M} - \boldsymbol{M} \boldsymbol{K} = \boldsymbol{r} \boldsymbol{s} ^{\mathrm T}\), a set of scalar master functions \(\{S^{(i,j)}\}\) are defined. We derive the evolution of scalar functions using the nonisospectral dispersion relations. Some explicit solutions are illustrated together with the analysis of their dynamics.
