(2+1)维长波短波共振相互作用方程的新精确行波解

New Exact Traveling Solutions of the (2+1) Dimensional Long Wave-short Wave Resonance Interaction Equations

利用扩展的双曲正切函数法获得了(2+1)维长波短波共振相互作用方程的多组新显式精确行波解.这些解包括孤立波解,周期解和实数解.

Applying the modified extended tanh - function methods, many types of new explicit traveling wave solutions of the （2 ＋ 1 ） dimensional long wave - short wave resonance interaction equations are obtained. These solutions include solitary wave solutions, periodic solutions and rational solutions.
