A CENTRAL LIMIT THEOREM WITH APPLICATIONS TO PERCOLATION, EPIDEMICS AND BOOLEAN MODELS

By Mathew D. Penrose.

Suppose X = (Xx)x in Zd is a white noise process, and H(B), defined for each lattice box B, is determined in a stationary way by the restriction of X to B. Using a martingale approach, we prove a central limit theorem (CLT) for H as B becomes large, subject to H satisfying a ``stabilization'' condition. This CLT is then applied to component counts for percolation and Boolean models, to the size of the big cluster for percolation on a box, and to the final size of a spatial epidemic.
