| Abstract: | The following partial differential equations are studied: generalized fifth-order KdV equation,water wave equation, Kupershmidt equation, couples KdV equation. The analytical solutions to these problems via using various ansatzes by introducing a second-order ordinary differential equation are found out. |
| Keywords: | nonlinear physical model ansatz method analytical solution |
