平面随机簇模型:标度关系

Planar random-cluster model: scaling relations

Hugo Duminil-Copin, Ioan Manolescu

摘要:

本文利用新的耦合技术研究了具有团簇权$q\in[1,4]$的$\mathbb Z^2$平面随机团簇模型的临界和近临界区。更精确地说,我们推导出了临界指数$β$,$γ$,$δ$,$η$,$ν$,$ζ$以及$α$(当$α\ge0$时)之间的标度关系。作为一个关键的输入,我们显示了在近临界状态下的交叉概率的稳定性,使用新的解释的边缘的混合率的影响的概念。作为一个副产品,我们推导出一个推广的Kesten的经典标度关系的伯努利渗流涉及“混合率”的临界指数$ι$取代四臂事件指数$ξ_4$。

英文摘要:

This paper studies the critical and near-critical regimes of the planar random-cluster model on $\mathbb Z^2$ with cluster-weight $q\in[1,4]$ using novel coupling techniques. More precisely, we derive the scaling relations between the critical exponents $β$, $γ$, $δ$, $η$, $ν$, $ζ$ as well as $α$ (when $α\ge0$). As a key input, we show the stability of crossing probabilities in the near-critical regime using new interpretations of the notion of influence of an edge in terms of the rate of mixing. As a byproduct, we derive a generalization of Kesten's classical scaling relation for Bernoulli percolation involving the ``mixing rate'' critical exponent $ι$ replacing the four-arm event exponent $ξ_4$.
