Generalised Oriented Site Percolation

I. Hartarsky, R. Szabo

2022, v.28, Issue 2


We consider a generalised oriented site percolation model (GOSP) on $\bbZ^d$ with arbitrary neighbourhood. The key additional difficulties as compared to standard oriented percolation (OP) are the lack of symmetry and, in two dimensions, of planarity. We establish that, despite these deficiencies, in the supercritical regime GOSP behaves qualitatively like OP.

Keywords: oriented percolation, contact process, probabilistic cellular automata
