摘要
本文利用贝尔多项式方法描述了地球物理布辛斯方程的双线性形式、双线性贝克隆变换和拉克斯对。从 Lax 对的意义上断言了上述方程的可积分性。达尔布变换用于产生周期解以及单次和 N 次偶次型解。使用 Hirota 双线性技术的几个步骤来说明多偶子、高阶呼吸器和流氓波的流动特性。对科里奥利力的各种波动力响应进行了仔细研究。
Bilinear Bäcklund transformation, Lax pair, Darboux transformation, multi-soliton, periodic wave, complexiton, higher-order breather and rogue wave for geophysical Boussinesq equation
This article describes the bilinear form, biliear Bäcklund transformation and Lax pair of the geophysical Boussinesq equation using the Bell polynomial approach. The integrability of the said equation is asserted in the sense of the Lax pair. The Darboux transformation is employed to produce periodic solutions as well as single and N-complexiton-type solutions. Several steps of the Hirota bilinear technique are used to illustrate the flow characteristics of multi-solitons, higher-order breathers and rogue waves. Every sort of wave dynamics response to the Coriolis force is carefully studied.
