Almost sharp sharpness for Poisson Boolean percolation

Probability 2022-09-05 v1

Abstract

We consider Poisson Boolean percolation on Rd\mathbb R^d with power-law distribution on the radius with a finite dd-moment for d2d\ge 2. We prove that subcritical sharpness occurs for all but a countable number of power-law distributions. This extends the results of Duminil-Copin--Raoufi--Tassion where subcritical sharpness is proved under the assumption that the radii distribution has a 5d35d-3 finite moment. Our proofs techniques are different from their paper: we do not use randomized algorithm and rely on specific independence properties of Boolean percolation, inherited from the underlying Poisson process. We also prove supercritical sharpness for any distribution with a finite dd-moment and the continuity of the critical parameter for the truncated distribution when the truncation goes to infinity.
