Stability in a Reaction-Diffusion Model of Mutualism

Abstract
A reaction-diffusion model for the mutualistic interaction of two species is studied. A condition for the dominance of an equilibrium point in the bistable case is obtained, generalizing results for the well-known scalar case. It is also shown that the “hair trigger effect” operates when the corresponding kinetic system has a single globally asymptotically stable interior equilibrium point.
