Applications of the Extended Simplest Equation Method to two nonlinear evolution equations

Gai Li-ta

Abstract

We successfully construct the new exact traveling wave solutions of the Joseph-Egri equation and the(2+1)-dimensional KP equation by using the extended simplest equation method.The exact traveling wave solutions with double arbitrary parameters,are expressed by the hyperbolic functions,the trigonometric functions and the rational functions respectively.When the parameters are taken as special values,some solitary wave solutions are derived from the hyperbolic function solutions.
