Liouville量子引力中光锥区域的SLE$_κ(ρ)$过程

SLE$_κ(ρ)$ processes in the light cone regime on Liouville quantum gravity

Konstantinos Kavvadias, Jason Miller

AI总结:

本文研究光锥区域SLE$_κ(ρ)$过程与LQG的关系,证明其在权重$(ρ+4)$量子楔上可粘合为相关稳定Lévy过程坐标所描述的树对,并推出大面双极有向随机平面图的标度极限。

摘要:

我们研究某些SLE$_κ(ρ)$过程与Liouville量子引力(LQG)之间的关系;这些过程是Schramm-Loewner演化在参数$κ$下的变体,其中需要追踪一个额外标记点。此类过程在$ρ>-2-κ/2$时均有定义,而在本工作中,我们将聚焦于光锥区域,即$κ\in(0,4)$且$\max(κ/2-4,-2-κ/2)<ρ<-2$。尽管普通SLE$_κ$曲线在$κ\in(0,4)$时是简单曲线,但这些过程会自交。我们证明,绘制在一个独立的、称为权重$(ρ+4)$量子楔的$\sqrtκ$-LQG曲面之上的这种过程,可以表示为一对树的粘合,这对树由一个相关$α$-稳定Lévy过程的两个坐标函数描述,其中$α=1-2(ρ+2)/κ$。结合另一项工作,这表明具有大面的双极有向随机平面图在标度极限下可等同于$κ\in(4/3,2)$时独立$\sqrtκ$-LQG曲面上的SLE$_κ(κ-4)$曲线。

英文摘要:

We study the relationship between certain SLE$_κ(ρ)$ processes, which are variants of the Schramm-Loewner evolution with parameter $κ$ in which one keeps track of an extra marked point, and Liouville quantum gravity (LQG). These processes are defined whenever $ρ> -2-κ/2$ and in this work we will focus on the light cone regime, meaning that $κ\in (0,4)$ and $\max(κ/2-4,-2-κ/2) < ρ< -2$. Such processes are self-intersecting even though ordinary SLE$_κ$ curves are simple for $κ\in (0,4)$. We show that such a process drawn on top of an independent $\sqrtκ$-LQG surface called a weight $(ρ+4)$-quantum wedge can be represented as a gluing of a pair of trees which are described by the two coordinate functions of a correlated $α$-stable Lévy process with $α= 1-2(ρ+2)/κ$. Combined with another work, this shows that bipolar oriented random planar maps with large faces can be identified in the scaling limit with an SLE$_κ(κ-4)$ curve on an independent $\sqrtκ$-LQG surface for $κ\in (4/3,2)$.
