高维度量图高斯自由场临界水平集的单臂指数

One-arm exponent of critical level-set for metric graph Gaussian free field in high dimensions

Zhenhao Cai, Jian Ding

AI总结:

本文证明高维(d>6)度量图上高斯自由场临界水平集的单臂概率渐近于 N^{-2},借鉴 Kozma-Nachmias 的临界键渗流结果与 Werner 的相似性猜想。

摘要:

本文研究度量图 $\widetilde{\mathbb{Z}}^d,d>6$ 上高斯自由场(GFF)的临界水平集。我们证明单臂概率(即原点连接到盒子 $B(N)$ 边界这一事件的概率)与 $N^{-2}$ 成正比,其中 $B(N)$ 以原点为中心,边长为 $2\lfloor N \rfloor$。我们的证明深受 Kozma 和 Nachmias [29] 的启发,他们证明了 $d\geq 11$ 时临界键渗流的类似结果;同时也受 Werner [51] 的启发,他猜想 GFF 水平集与键渗流在一般情形下具有相似性,并针对多种几何方面证明了这一联系。

英文摘要:

In this paper, we study the critical level-set of Gaussian free field (GFF) on the metric graph $\widetilde{\mathbb{Z}}^d,d>6$. We prove that the one-arm probability (i.e. the probability of the event that the origin is connected to the boundary of the box $B(N)$) is proportional to $N^{-2}$, where $B(N)$ is centered at the origin and has side length $2\lfloor N \rfloor$. Our proof is hugely inspired by Kozma and Nachmias [29] which proves the analogous result of the critical bond percolation for $d\geq 11$, and by Werner [51] which conjectures the similarity between the GFF level-set and the bond percolation in general and proves this connection for various geometric aspects.
