摘要
运用1种改进的多线性分离变量法,将(2+1)维色散长波方程约化为含有关于{x,t}和{y,t}的任意函数的1个线性演化方程,并通过进一步改进这种方法,寻找形如f=p(x,y,t)+q(y,t)形式的解,从而得到原方程的一些包含分离变量形式的新解.
By using a improved multi-linear variable separation approach,the(2+1)-dimensional dispersive long-wave equation is reduced to a linear evolution equation with two arbitrary functions of {x,t} and{y,t}.Through further improving the method we look for the solution in the form f=p(x,y,t)+q(y,t).Some new solutions of the original equations which include the variable separation solutions are obtained.
