Properties of the asymptotic nA+mB->C reaction-diffusion fronts

We discuss, at the mean-field level, the asymptotic shape of the reaction fronts in the general nA+mB->C reaction-diffusion processes with initially separated reactants, thus generalizing to arbitrary reaction-order kinetics the work done by Galfi and Racz for the case n=m=1. Consequences for the formation of Liesegang patterns are discussed.
