TURING PATTERNS IN A SINGLE-STEP AUTOCATALYTIC REACTION

Stable Turing patterns are presented in the simplest reaction-diffusio n system containing a single autocatalytic step in a continuously fed unstirred reactor. In the one-variable homogeneous system exhibiting o nly bistability, the spatial instability arises from the decoupling of the species by unequal diffusion. The results suggest the possibility of experimentally finding Turing instability among the relatively com mon bistable chemical systems.
