Resumen

In this paper, we answer the question about the existence of theminimal speed of front propagation in a delayed version of the Murray modelof the Belousov-Zhabotinsky BZ chemical reaction. It is assumed that thekey parameter r of this model satis es 0 < r 1 that makes it formallymonostable. By proving that the set of all admissible speeds of propagationhas the form c ;+1, we show here that the BZ system with r 2 0; 1 isactually of the monostable type in general, c is not linearly determined. Wealso establish the monotonicity of wavefronts and present the principal termsof their asymptotic expansions at in nity in the critical case r = 1 inclusive.Nota general
