D. Balboni et al., UNIVERSALITY OF A CLASS OF ANNIHILATION COAGULATION MODELS, Physical review. E, Statistical physics, plasmas, fluids, and related interdisciplinary topics, 52(6), 1995, pp. 6220-6226
A class of d-dimensional reaction-diffusion models interpolating conti
nuously between the diffusion-coagulation and the diffusion-annihilati
on models is introduced. Exact relations among the observables of diff
erent models are established. For the one-dimensional case, it is show
n how correlations in the initial state can lead to nonuniversal ampli
tudes for time-dependent particle density.
