Abstract
The spatiotemporal structure of reactive media supporting a solitary spiral wave is studied for systems where the local reaction law exhibits a period-doubling cascade to chaos. This structure is considerably more complex than that of simple period-1 oscillatory media. As one moves from the core of the spiral wave the local dynamics takes the form of perturbed period-doubled orbits whose character varies with spatial location relative to the core. An important feature of these media is the existence of a curve where the local dynamics is effectively period-1. This curve arises as a consequence of the necessity to reconcile the conflict between the global topological organization of the medium induced by the presence of a spiral wave and the topological phase space structure of local orbits determined by the reaction rate law. Due to their general topological nature, the phenomena described here should be observable in a broad class of systems with complex periodic behavior.
