NEW SOLITONS AND PERIODIC SOLUTIONS FOR THE KADOMTSEV-PETVIASHVILI EQUATION

In this paper, the sine-cosine, the standard tanh and the ex- tended tanh methods has been used to obtain solutions of the Kadomstev- Petviashvili(KP) equation. New solitons solutions and periodic solutions are formally derived. The change of parameters, that will drastically change char- acteristics of the equation, is examined.
