Abstract

The stability of a steadily rotating spiral solution in the outer scaling region of an excitable medium is calculated. The spiral is shown to be stable, suggesting that the transition to meandering is due to a core region instability. The consequences of the coupling of perturbations in the core to the outer region are shown to be consistent with numerical studies.
