THE EFFECT OF WAVE-FRONT INTERACTIONS ON PATTERN-FORMATION IN EXCITABLE MEDIA

Research output: Chapter in Book/Report/Conference proceedingChapterpeer-review

Abstract

The nonlinear interactions of solitary wavefronts in excitable media are determined by the manner of recovery to the rest state. The distance between a pair of wavefronts tends to lock at one of countably many possible values in the case of oscillatory recovery, while it increases indefinitely when the recovery is monotonic. We derive these results from the basic reaction diffusion equations and study the implications on pattern formation in one and two space dimensions. In particular we demonstrate how spatiotemporal complexity may arise in one dimension, and discuss possible consequences of the interplay between wavefront-interactions and curvature in two dimensions.
