Survival and Percolation Probabilities in the Field Theory of Growth Models
Abstract
Description
Survival and percolation probabilities are most important quantities in the theory and in the application of growth models with spreading. We construct field theoretical expressions for these probabilities which are feasible for perturbation expansions. The outstanding role of the absorbing noise is stressed to obtain survival probabilities monotonic decreasing with time. We briefly consider some fundamental growth models equipped with absorbing noise which are representations of known universality classes of spreading phenomena. The critical scaling properties of their survival and percolation and probabilities are stated. In an appendix we consider shortly the renormalized field theory of compact directed percolation.
