摘要
对文献给出的(2+1)维耗散长波方程的变量分离解作了进一步的研究,首先说明拓展的F/G展开法得到的解等价于拓展的tanh展开法得到的解;然后通过一个变换以及修正的齐次平衡法,给出了(2+1)维耗散长波方程更多的精确解.
Further study on the exact solutions for(2+1)-dimensional dispersive long wave equation has been done.Firstly,we show that the solutions obtained by the extended F/G-expansion method are equivalent to the solutions obtained by the extended tanh-expansion method.Then,through a transformation and the modified homogeneous balance method,the more exact solutions for(2+1)-dimensional dissipative long wave equation are given.
