摘要
研究了(2+1)-维色散长波系统.首先,确定该系统的对称群,此对称群含有3个任意的光滑函数,然后利用某些子群,把系统约化为热传导方程和第二型Pain levé方程.
In this paper, we study on the (2 + 1 ) dimensional dispersive long-wave system. First, we determine the symmetry group of the system. It turns out that the symmetry group contains three arbitrary smooth functions. Then, we reduce the system to the heat equation and the second Painlevé equation by using some subgroups.
