Abstract

In this paper, the Fisher equation is analysed. One of its travelling wave solution is obtained by comparing it with KdV–Burgers (KdVB) equation. Its amplitude, width and speed are investigated. The instability for the higher order disturbances to the solution of the Fisher equation is also studied.
