Universality class for extinction-survival phase transition in one dimension

Abstract
In one-dimension irreversibly interacting-particle systems exhibiting extinction-survival phase transitions, such as the contact process and branching annihilation random walk, are analyzed using a space-time renormalization-group method. Strong positive evidence is shown for the conjecture that all ‘‘reasonably’’ defined interacting-particle systems with nearest-neighbor interactions belong to the same universality class of directed percolation.
