We examine the long-time behaviour of A + B(static) → 0 reaction-diffusion systems with initially separated species A … and B. All of our analysis is carried out for arbitrary (positive) values of the diffusion constant DA of particles A and … numerical solutions of the mean-field reaction-diffusion equation. …
