Abstract

Computer simulations on binary reactions of random walkers (A + A → A) on two- and three-dimensional percolation clusters bear out the recent superuniversality conjecture (integrated reaction rate α t213). Moreover, the fractal-to-euclidean crossover (t213 to t dependence) parallels that of the single walker.
