Abstract
A modified (G'/G)- expansion method is proposed to construct hyperbolic, trigonometric and
rational function solutions of nonlinear evolution equations which can be thought of as the generalization of
the (G'/G)- expansion method given recently by M.Wang et al . To illustrate the validity and advantages of
this method, the (1+1)-dimensional Hirota-Ramani equation and the (2+1)-dimensional Breaking soliton
equation are considered and more general traveling wave solutions are obtained. It is shown that the proposed
method provides a more general powerful mathematical tool for solving nonlinear evolution equations in
mathematical physics.
