The contact process with dynamic edges on $\mathbb{Z}$

Probability 2020-10-15 v3

Abstract

We study the contact process running in the one-dimensional lattice undergoing dynamical percolation, where edges open at rate vpvp and close at rate v(1p)v(1-p). Our goal is to explore how the speed of the environment, vv, affects the behavior of the process. We show in particular that for small enough vv the process dies out, while for large vv the process behaves like a contact process on Z\mathbb{Z} with rate λp\lambda p, so it survives if λ\lambda is large. We also show that if vv and pp are small then the network becomes immune, in the sense that the process dies out for any infection rate λ\lambda, while if pp is sufficiently close to 11 then for all v>0v>0 survival is possible for large enough λ\lambda.
