Nonpercolation conjecture for Brownian-perturbed square packing

Let Π0s\Pi_0^\mathrm{s} be the vertices of the square lattice with side length 11, and let Πϵs\Pi_\epsilon^\mathrm{s} be obtained by moving those nodes independently according to Brownian motion for time ϵ\epsilon. Let R(Πϵs)R(\Pi_\epsilon^\mathrm{s}) be the union of balls of radius 1/21/2 centered at the moved nodes. Square-packing nonpercolation conjecture. For any ϵ>0\epsilon>0, all components of R(Πϵs)R(\Pi_\epsilon^\mathrm{s}) are finite almost surely. This conjecture asserts that every positive Brownian perturbation destroys percolation in the square packing, motivated by the subcritical edge-intersection probability described in the source.
