Abstract

Physical Sciences Physics Physics, Multidisciplinary Science & Technology
Very recently, Wang et al (2008 Phys. Lett. A 327 417-23) proposed a method, namely the (G'/G)-expansion method, for constructing multiple travelling wave solutions of nonlinear evolution equations arising in mathematical physics. They believe that the (G'/G)-expansion method is a new method and more travelling wave solutions of many nonlinear evolution equations can be obtained. In this paper, we show that the (G'/G)-expansion method is equivalent to the extended tanh function method.
