Abstract

We study inhomogeneous Bernoulli bond percolation on the graph G×ZG \times \mathbb{Z}, where GG is a connected quasi-transitive graph. The inhomogeneity is introduced through a random region RR around the origin axis {0}×Z\{0\}\times\mathbb{Z}, where each edge in RR is open with probability qq and all other edges are open with probability pp. When the region RR is defined by stacking or overlapping boxes with random radii centered along the origin axis, we derive conditions on the moments of the radii, based on the growth properties of GG, so that for any subcritical pp and any q<1q<1, the non-percolative phase persists.
