| Abstract: | An analysis is made of critical perturbations which initiate the evolution of instability in a monostable active medium described
by a reaction-diffusion equation. A group-theoretical analysis of the problem yields an analytic expression for the energy
of the critical perturbations. The results may be important for analyses of stability with respect to external perturbations
of a wide range of active media.
