The (G'/G)-Expansion Method for the Sine-Gordon Equation, Sinh-Gordon Equation and Liouville Equaiton

摘要

In this paper, the (G'/G)-expansion method is applied to find the exact solutions for Sine-Gordon equation, Sinh-Gordon equation and Liouville equaiton. The (G'/G)-expansion method is an effective method in investigating exact traveling wave solutions to nonlinear evolution equations (NLEEs) in the field of applied mathematics, mathematical physics and engineering.
