Abstract
We study noise-induced front propagation in a bistable system of the activa tor-inhibitor type. By varying the intensity of the multiplicative noise, t he velocity of the front exhibits a transition to a bistable regime, where the actual velocity and direction of front motion depends mainly on the (ra ndom) initial conditions.
