摘要:

描述长波-短波共振相互作用的模型具有从流体动力学到等离子体物理的许多物理应用。我们认为在这里的Yajima-Oikawa-Newell(YON)模型,这是最近推出的结合两个长波-短波,可积模型,一个由Yajima-Oikawa提出的,另一个由Newell的相互作用项。新的YON模型包含两个任意的耦合常数,并且对于这些耦合常数的任何值,它仍然是可积的-在拥有拉克斯对的意义上。对于这两个参数的特殊选择,它归结为Yajima-Oikawa或Newell系统。我们构建家庭的周期性和孤立波的解决方案,这显示了很长的波的产生。我们还计算了一些守恒律的显式表达式。

英文摘要:

Models describing long wave-short wave resonant interactions have many physical applications from fluid dynamics to plasma physics. We consider here the Yajima-Oikawa-Newell (YON) model, which has been recently introduced combining the interaction terms of two long wave-short wave, integrable models, one proposed by Yajima-Oikawa, and the other one by Newell. The new YON model contains two arbitrary coupling constants and it is still integrable - in the sense of possessing a Lax pair - for any values of these coupling constants. It reduces to the Yajima-Oikawa or the Newell systems for special choices of these two parameters. We construct families of periodic and solitary wave solutions, which display the generation of very long waves. We also compute the explicit expression of a number of conservation laws.
