WAVE-INDUCED CHEMICAL CHAOS

Spatiotemporal chaos in a two-variable, cubic autocatalator model with equal diffusivities of the species is described. The interplay betwee n an unstable homogeneous state and propagating fronts which return th e system to that state gives rise to a reinjection mechanism for chaot ic behavior. Extreme sensitivity to initial conditions in both space a nd time and a rapid falloff of the spatial correlation function are ex hibited in the chaotic regime.
