For $d=1,2$, consider the harness process on ${\mathbb Z}^d\setminus\{0\}$ with generator $L^{{\mathbb Z}^d\setminus\{0\}}$, and let $\eta^{{\mathbb Z}^d\setminus\{0\}}_t$ denote i…

Let $d\geq 3$. The harness process on ${\mathbb Z}^d$ has generator $L^{{\mathbb Z}^d}$, and let $\eta^{{\mathbb Z}^d}_t$ denote its infinite-volume stationary configuration. An in…
