The (G`/G)-expansion Method a Special Case of the Generalized tanh-function Type Method
نویسنده
چکیده
In this paper a generalized tanh-function type method is proposed by using the idea of the transformed rational function method. We shown that the (G`/G)-expansion method is a special case of the generalized tanh-function type method, so the (G`/G) -expansion method is included by the transformed rational function method. We demonstrate that all solutions obtained by the (G`/G)-expansion method are not new and were found by the generalized tanh-function type method. In comparison with all solution expressions obtained by the generalized tanh-function type method, we find that solution expressions obtained by the (G /̀G)-expansion method are very cumbersome.

A Generalized Tanh-Function Type Method and the(G'/G) -Expansion Method for Solving
In this paper a generalized tanh-function type method is proposed by using the idea of the transformed rational function method. We show that the G G -expansion method is a special case of the generalized tanh-function type method, so the G G -expansion method is considered as a special deformation application of the transformed rational function method. We demonstrate that all solutio...

متن کاملApplication of the new extended (G'/G) -expansion method to find exact solutions for nonlinear partial differential equation
In recent years, numerous approaches have been utilized for finding the exact solutions to nonlinear partial differential equations. One such method is known as the new extended (G'/G)-expansion method and was proposed by Roshid et al. In this paper, we apply this method and achieve exact solutions to nonlinear partial differential equations (NLPDEs), namely the Benjamin-Ono equation. It is est...
