基于Galton-Watson树的沙堆平均场雪崩尺寸指数

Mean-field avalanche size exponent for sandpiles on Galton-Watson trees

Antal Jarai, Wioletta M. Ruszel, Ellen Saada

摘要:

我们发现,在无限高尔顿-沃森树上的阿贝尔沙堆中,总雪崩有超过$t$ topplings的概率衰减为$t^{-1/2}$。我们证明淬火和退火的界限,在适当的时刻条件下。我们的证明是基于对Morris(2003)的电导鞅的分析,该分析之前被Lyons,Morris和Schramm(2008)用于研究$\mathbb{Z}^d$,$d\geq 3$和其他瞬态图上的均匀生成森林。

英文摘要:

We show that in abelian sandpiles on infinite Galton-Watson trees, the probability that the total avalanche has more than $t$ topplings decays as $t^{-1/2}$. We prove both quenched and annealed bounds, under suitable moment conditions. Our proofs are based on an analysis of the conductance martingale of Morris (2003), that was previously used by Lyons, Morris and Schramm (2008) to study uniform spanning forests on $\mathbb{Z}^d$, $d\geq 3$, and other transient graphs.
