摘要

本研究探讨了 (2+1)-dimensional Kadomtsev-Petviashvili 型方程,该方程描述了海洋学、流体动力学和浅水中的非线性波浪行为模式和特性。首先,采用 Hirota 双线性形式为治理模型开发了各种块波、带状孤子波和周期波解决方案。此外,利用扩展的修正辅助方程映射技术和 Adomian 分解算法生成了一些有趣的行波和半解析孤子。此外,为了确定绝对误差,我们将近似结果和孤子结果并列起来。此外,我们还对调控模型的稳定性分析和调制不稳定性进行了广泛的讨论,以验证科学计算的有效性。此外,我们还提供了包括等值线图、二维和三维模型在内的图形描述,有助于理解模型解决方案所呈现的行为和动态。本研究的发现非常新颖,对孤子动力学和数学物理学做出了重大贡献。

Lumps, solitons, modulation instability and stability analysis for the novel generalized (2+1)-dimensional nonlinear model arising in shallow water
In this study, the (2+1)-dimensional Kadomtsev–Petviashvili type equation is investigated that describes the nonlinear wave patterns of behavior and properties in oceanography, fluid dynamics, and shallow water. Firstly, the Hirota bilinear form is implemented to develop a variety of lump, strip soliton and periodic waves solutions for the governing model. Furthermore, some interesting traveling and semi-analytical solitons are generated by availing the extended modified auxiliary equation mapping technique and the Adomian decomposition algorithm. Moreover, in order to determine the absolute error, we have constructed a juxtapose of approximate and soliton results. Additionally, we deliberate the stability analysis and the modulation instability for the governing model extensively to validate the scientific computations. Moreover, the graphical portrayals which include contour plots, 2D and 3D models are illustrated that are useful for understanding the behaviors and dynamics presented by the model’s solutions. The findings of current study are quite novel and make a big contribution to soliton dynamics and mathematical physics.
