An improved (G'/G)- expansion method for solving nonlinear evolution equations

摘要

In this paper, we apply improved (G ′ /G)-expansion method to discover a strategy for the approximate solution of nonlinear evolution equations (NLEEs). The given NLEEs through substitution are converted into a nonlinear ordinary differential equation. The travelling wave solution is approximated by the (G ′ /G) -expansion method with unknown parameters.
