An unusual method for the analysis of a class of reaction-diffusion systems is presented. Through an integration the system is reduced to a single reaction-diffusion equation with inhomogeneous terms arising from the initial conditions. The method is limited in its applicability but very quickly yields important results when it can be used. Some applications in epidemiology, chemistry, mycology and ecology are given. © 1991.
