Oriented bond-site percolation in random environment and contact processes with periodic recovery
Abstract
We investigate oriented bond-site percolation on the planar lattice in which entire columns are stretched. Generalising recent results by Hil\'ario et al., we establish non-trivial percolation under a (1+)-th moment condition on the stretches and use this to prove survival of contact processes with periodic recoveries as well as in random environments.
