Explicit solutions of Fisher's equation for a special wave speed

, and . Bulletin of Mathematical Biology, 41 (6): 835--840 (November 1979)

Abstract

The travelling waves for Fisher's equation are shown to be of a simple nature for the special wave speeds $$c = 5/(6) $$. In this case the equation is shown to be of Painlevé type, i.e. solutions admit only poles as movable singularities. The general solution for this wave speed is found and a method is presented that can be applied to the solution of other nonlinear equations of biological and physical interest.
