چکیده
In this paper,the traditional G′/G-expansion method is improved and a generalized G′/G-expansion method is proposed to seek exact solutions of nonlinear evolution equations.And we choose Benjamin-Bona-Mahony equation,(2+1) dimensional generalized Zakharov-Kuznetsov equation and variant Bousinessq equations to illustrate the validity and advantages of the proposed method.It is shown that the proposed method is direct,effective because we can obtain not only triangular periodic wave solutions and hyperbolic function solutions,but also exponential function solutions and Jacobi elliptic function solutions.Moreover,it can also be used for many other nonlinear evolution equations in mathematical physics.

THE MODIFIED (w/g)-EXPANSION METHOD AND ITS APPLICATIONS FOR SOLVING THE MODIFIED GENERALIZED VAKHNENKO EQUATION
The modified (w/g)-expansion method for finding traveling wave solutions of nonlinear evolution equations is presented in this paper, which can be thought of as the generalization of the well-known (G′/G)-expansion method given recently by Wang et al. When the w and g are taken special choices, some familiar expansion methods can be obtained. Based on these interesting results, we further give ...
متن کاملA 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 کاملGroup Generalized Interval-valued Intuitionistic Fuzzy Soft Sets and Their Applications in\ Decision Making
Interval-valued intuitionistic fuzzy sets (IVIFSs) are widely used to handle uncertainty and imprecision in decision making. However, in more complicated environment, it is difficult to express the uncertain information by an IVIFS with considering the decision-making preference. Hence, this paper proposes a group generalized interval-valued intuitionistic fuzzy soft set (G-GIVIFSS) which conta...
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...
