| Abstract: | By means of the improved double functions method, many kinds of exact travelling wave solutions for a class of nonlinear evolution equations are obtained, which contain soliton wave solutions and periodic solutions. The results obtained by the homogeneous balance method are extended, meantime, many kinds of new soliton wave solutions and periodic solutions are obtained. With the aid of Mathematics, the method can be partly carried out on computer. |
