FUZZY TRANSITION REGION IN A ONE-DIMENSIONAL COUPLED-STABLE-MAP LATTICE

A coupled-map lattice showing complex behavior in the presence of a fully negative Lyapunov spectrum is considered. A dynamical phase transition from ``frozen'' disorder to chaoticlike evolution upon changing diffusive coupling is studied in detail. Various indicators provide a coherent description of the scenario: the existence of a finite transition region characterized by an irregular alternancy of periodic and chaotic evolution
