In contrast to previous investigations, we find no phase transition whenk4≠0 andd<4. Fork4=0,k3≠0, and 1≦d<4, we find a second-order phase transition which is in the same universality class as the transition in Schlögl's first model. Only ford≧4 we do find the first-order transition found also by previous authors.
These claims are supported by extensive Monte Carlo calculations for various realizations of this process on discrete space-time lattices.
