| Abstract: | Using some variable transformations and analytical integration, the analytical solitary wave solutions are obtained for the dispdrive DNLS equation and dissipative MKdV equation, which describe the propagation of Alfven waves in various plasma medium. Meanwhile, the ekistence conditions of soliton-like solutions are given. |
