Exact Solutions for the Compound KdV-Burgers Equation Using the Improved (G'/G)-Expansion Method

摘要

Exact solutions of nonlinear partial differential equation are major subject in the study of nonlinear science. In this paper, with the aid of computer algebraic system mathematica, the compound KdV-Burgers equation are investigated by using the improved (G'/G)-expansion method. As a result, many exact solutions are obtained which including hyperbolic function solutions, trigonometric function solutions and rational function solutions.
