Exact Solutions for Nonlinear Evolution Equations Via Extended Projective Riccati Equation Expansion Method
نویسنده
چکیده
Abstract: By means of a simple transformation, we have shown that the generalized-Zakharov equations, the coupled nonlinear Klein-Gordon-Zakarov equations, the GDS, DS and GZ equations and generalized Hirota-Satsuma coupled KdV system can be reduced to the ellipticlike equations. Then, the extended projective Riccati equation expansion method is used to obtain a series of solutions including new solitary wave solutions,periodic and rational solutions. The method is straightforward and concise, and its applications is promising. c © Electronic Journal of Theoretical Physics. All rights reserved.
