Gibbsianness of locally thinned random fields

Probability 2022-01-11 v1

Abstract

We consider the locally thinned Bernoulli field on Zd\mathbb Z^d, which is the lattice version of the Type-I Mat\'ern hardcore process in Euclidean space. It is given as the lattice field of occupation variables, obtained as image of an i.i.d. Bernoulli lattice field with occupation probability pp, under the map which removes all particles with neighbors, while keeping the isolated particles. We prove that the thinned measure has a Gibbsian representation and provide control on its quasilocal dependence, both in the regime of small pp, but also in the regime of large pp, where the thinning transformation changes the Bernoulli measure drastically. Our methods rely on Dobrushin uniqueness criteria, disagreement percolation arguments, and cluster expansions.
