摘要

从正 Gardner-Kadomtsev-Petviashvili 方程的双线性形式出发，借助扩展的同室检验方法，得到了呼吸型和 N 呼吸型解决方案。通过三维图、密度图和等值线图说明了呼吸型、单呼吸、双呼吸和三呼吸解，并选择了一些适当的参数值，以更好地展示它们的时间演化过程。

Breather-type and N-breather solutions for the positive Gardner-KP equation

Starting from the bilinear form of the positive Gardner–Kadomtsev–Petviashvili equation, breather-type and N-breather solutions are obtained with the help of the extended homoclinic test approach. Breather-type, one-breather, two-breather and three-breather solutions are illustrated through 3D plots, density plots and contour plots and some appropriate parameter values have been chosen to better demonstrate their time evolution.
