SPIRAL WAVES IN A CYCLIC CELLULAR-AUTOMATON MODEL FOR EXCITABLE MEDIA

We present a cyclic cellular automaton for excitable media. The model exhibits the complex dynamics of patterns observed in excitable media. Spatial patterns dynamics provides an important example of spatio-tem poral self-organization in distributed active systems. The global beha vior of the cellular automaton model is described in terms of point co rrelation functions. The Fouries analysis pointed out the quasi-oscill atory and chaotic behavior of these functions.
