Rigidity of harmonic functions on the supercritical percolation cluster

Probability 2024-04-01 v2 Analysis of PDEs

Abstract

We use ideas from quantitative homogenization to show that nonconstant harmonic functions on the percolation cluster cannot satisfy certain structural constraints, for example, a Lipschitz bound. These unique-continuation-type results are false on the full lattice and hence the disorder is utilized in an essential way.
