Using G′G-expansion method to seek the traveling wave solution of Kolmogorov–Petrovskii–Piskunov equation

摘要

In this paper, we use the G′G-expansion method to seek the traveling wave solutions of the Kolmogorov–Petrovskii–Piskunov equation. The solutions obtained in this paper are more general than the solutions given in Refs. [23], [24], [25], and the computation procedure is much simpler. It is shown that the G′G-expansion method provides a very effective and powerful tool for solving nonlinear equations in mathematical physics.
