| Abstract: | Some classes of three variables and multi- variables coupled nonlinear equations, which have crucial significance, are pres ented in this paper. These systems of three variables and multi-variables coupl ed nonlinear wave equations are composed of the combined form of the higher modi fied KdV equation and the KdV equation. It is shown that these systems of couple d nonlinear equations possess solitary wave solutions. Several forms of solitarywave solutions from these coupled nonlinear wave equations have been obtained.Some comments are made. |
| Keywords: | nonlinear evolution equations exact solitary wave-s olution KdV equation |
