Survival and Percolation Probabilities in the Field Theory of Growth Models
Hans-Karl Janssen
Survival and percolation probabilities are most important quantities in the theory and in the application of growth models with spreading. We construct field theoretical expression…

Directed Percolation has Colors and Flavors
Hans-Karl Janssen
A model of directed percolation processes with colors and flavors that is equivalent to a population model with many species near their extinction thresholds is presented. We use r…

On Coupled Directed Percolation Processes: A Unifying View
H. K. Janssen
It is shown that the universal critical properties of two recently introduced coupled directed percolation processes can be described by a single rapidity reversal invariant stocha…
