Quenched local limit theorem for random conductance models with long-range jumps

Probability 2024-04-11 v2

Abstract

We establish the quenched local limit theorem for reversible random walk on Zd\Z^d (with d2d\ge 2) among stationary ergodic random conductances that permit jumps of arbitrary length. The proof is based on the weak parabolic Harnack inequalities and on-diagonal heat-kernel estimates for long-range random walks on general ergodic environments. In particular, this partly solves \cite[Open Problem 2.7]{BCKW}, where the quenched invariance principle was obtained. As a byproduct, we prove the maximal inequality with an extra tail term for long-range reversible random walks, which in turn yields the everywhere sublinear property for the associated corrector.
