Active-to-absorbing phase transition subjected to the velocity fluctuations in the frozen limit case

Abstract

The directed bond percolation process is studied in the presence of com- pressible velocity fluctuations with long-range correlations. We discuss a construction of a field theoretic action and a way of obtaining its large scale properties using the perturbative renormalization group. The most interest- ing results for the frozen velocity limit are given.
