Transformations of dispersionless partial differential equations and exact solutions |
|
| Abstract: | By approximate reduction,three nonlinear physical equations are changed into a kind of dispersionless partial differential equations which are converted into the first order quasilinear hyperbolic equation via transformations.The exact solutions of dispersionless partial differential equations can be obtained by using the solutions of quasilinear hyperbolic equation. |
