Dissipative structures in chemical oscillations with concentrations-dependent frequency

Abstract

A general model for the propagation of chemical waves is proposed for a given class of chemical oscillations. This model gives a satisfactory qualitative account of the dissipative structures observed in the Belousov-Zhabotinskii reaction. The generality of this model makes it useful for predicting the possibility of chemical waves when the experimentally observed oscillations have a concentration-dependent frequency.
