Stochastic integrability of heat-kernel bounds for random walks in a balanced random environment

X Guo, HV Tran - Electronic Journal of Probability, 2024 - projecteuclid.org
In Z d, d≥ 2, we consider random walks in a balanced random environment with a finite
range of dependence. We first obtain both positive and negative exponential moment …
