AI总结:

本文为平面临界$q$-态Potts自旋簇引入并显式计算连续统三点连通常数,与虚DOZZ公式相差一个几何常数,并回答了Delfino等人提出的问题。

摘要:

最近,Ang--Cai--Sun--Wu(2024)确定了二维临界逾渗的三点连通常数,证实了Delfino和Viti(2010)的预测。在本文中,我们研究平面临界$q$-态Potts自旋簇的类似问题。我们引入了一个连续统三点连通常数并显式计算了它。在Potts自旋簇的标度极限猜想下,该量与三个点位于同一自旋簇中的适当归一化概率的标度极限一致。所得公式与虚DOZZ公式一致,相差一个具有几何解释的显式$q$依赖常数。这回答了Delfino--Picco--Santachiara--Viti(2013)提出的一个问题。证明利用了CLE与LQG之间的耦合,以及Miller--Sheffield--Werner(2017)和Köhler-Schindler与Lehmkühler(2025)给出的$q$-态Potts标度极限的BCLE描述。

英文摘要:

Recently, Ang--Cai--Sun--Wu (2024) determined the three-point connectivity constant for two-dimensional critical percolation, confirming a prediction of Delfino and Viti (2010). In this paper, we address the analogous problem for planar critical $q$-state Potts spin clusters. We introduce a continuum three-point connectivity constant and compute it explicitly. Under the scaling-limit conjecture for Potts spin clusters, this quantity coincides with the scaling limit of the properly normalized probability that three points lie in the same spin cluster. The resulting formula agrees with the imaginary DOZZ formula up to an explicit $q$-dependent constant with a geometric interpretation. This answers a question from Delfino--Picco--Santachiara--Viti (2013). The proof exploits the coupling between CLE and LQG, together with the BCLE descriptions of $q$-state Potts scaling limits due to Miller--Sheffield--Werner (2017) and Köhler-Schindler and Lehmkühler (2025).
