论文摘要

在本文中,考虑了一个广义的长波短波共振相互作用系统,该系统描述了流体动力学,等离子体物理学和非线性光学的短波与长波之间的非线性相互作用。使用Hirota双线方法,推导了一般的$ n $ bright和$ n $ -dark soliton解决方案,并获得了其革兰氏决定性形式。基本明亮的孤子解决方案的一个特殊特征是,通常,它的行为与Korteweg-Devries Soliton一样。但是,在特殊条件下,当它失去幅度依赖性速度特性时,它也类似于非线性schrödingersoliton。基本的深色 - 岩石解决方案根据波参数的选择,在短波组件中接受反黑,灰色和完全黑色的孤子轮廓。另一方面,像长波组件中总是出现明亮的孤子轮廓。渐近分析表明,明亮的和深色的孤子都会在有限的相移中经历弹性碰撞。除此之外,通过调整相移状态,我们指出了明亮的孤子之间存在共振相互作用的存在。此外,在特殊的速度共振条件下,我们提出了各种类型的明亮和深色孤子结合状态。同样,通过固定相对于长波和短波组件之间的相互作用的相位因子和系统参数$β$,证明了与获得的呼吸溶液相关的不同类型的轮廓。

In this paper, a generalized long-wave short-wave resonance interaction system, which describes the nonlinear interaction between a short-wave and a long-wave in fluid dynamics, plasma physics and nonlinear optics, is considered. Using the Hirota bilinear method, the general $N$-bright and $N$-dark soliton solutions are deduced and their Gram determinant forms are obtained. A special feature of the fundamental bright soliton solution is that, in general, it behaves like the Korteweg-deVries soliton. However, under a special condition, it also behaves akin to the nonlinear Schrödinger soliton when it loses the amplitude dependent velocity property. The fundamental dark-soliton solution admits anti-dark, grey, and completely black soliton profiles, in the short-wave component, depending on the choice of wave parameters. On the other hand, a bright soliton like profile always occurs in the long-wave component. The asymptotic analysis shows that both the bright and dark solitons undergo an elastic collision with a finite phase shift. In addition to these, by tuning the phase shift regime, we point out the existence of resonance interactions among the bright solitons. Furthermore, under a special velocity resonance condition, we bring out the various types of bright and dark soliton bound states. Also, by fixing the phase factor and the system parameter $β$, corresponding to the interaction between long and short wave components, the different types of profiles associated with the obtained breather solution are demonstrated.
