Are damage spreading transitions generically in the universality class of directed percolation?

Abstract

We present numerical evidence for the fact that the damage spreading\ntransition in the Domany-Kinzel automaton found by Martins {\\it et al.} is in\nthe same universality class as directed percolation. We conjecture that also\nother damage spreading transitions should be in this universality class, unless\nthey coincide with other transitions (as in the Ising model with Glauber\ndynamics) and provided the probability for a locally damaged state to become\nhealed is not zero.\n
