标题： Collision of Multimode Dromions and a Firewall in the Two Component Long Wave Short Wave Resonance Interaction Equation

摘要： 在本文中，我们研究了两组分长波短波共振相互作用（2CLSRI）方程，并表明它具有Painleve性质。 然后，我们适当利用最近发展的截断Painleve方法，为短波成分$S^{(1)}$和$S^{(2)}$生成指数局域解，而长波 L 仅具有线性孤子。 驱动短波$S^{(1)}$和$S^{(2)}$在 y 方向的指数局域解具有不同的能量（强度），被称为“多模态孤子”。 我们还观察到，多模态孤子会发生模内非弹性碰撞，而模式之间的防火墙的存在阻止了模式之间的能量转换。 显示英文摘要

摘要： In this paper, we investigate the two component long wave short wave resonance interaction (2CLSRI) equation and show that it admits the Painleve property. We then suitably exploit the recently developed truncated Painleve approach to generate exponentially localized solutions for the short wave components $S^{(1)}$ and $S^{(2)}$ while the long wave L admits line soliton only. The exponentially localized solutions driving the short waves $S^{(1)}$ and $S^{(2)}$ in the y direction are endowed with different energies (intensities) and are called "multimode dromions". We also observe that the multimode dromions suffer intramodal inelastic collision while the existence of a firewall across the modes prevents the switching of energy between the modes.
