带边界的均匀四边形剖分的尺度极限分类

Classification of scaling limits of uniform quadrangulations with a boundary

Erich Baur, Grégory Miermont, Gourab Ray

摘要:

研究了具有边界的均匀随机平面四边形在其尺度趋于无穷大时的非紧尺度极限。根据边界大小的渐近行为和比例因子的选择,我们观察到不同的极限度量空间。在著名的对象,如布朗平面或无限连续随机树,我们构造了两个新的单参数家庭的度量空间,出现的标度限制:布朗半平面与偏度参数$θ$和无限体积布朗圆盘的周长$σ$。我们还获得了各种耦合和极限结果澄清这些对象之间的关系。

英文摘要:

We study non-compact scaling limits of uniform random planar quadrangulations with a boundary when their size tends to infinity. Depending on the asymptotic behavior of the boundary size and the choice of the scaling factor, we observe different limiting metric spaces. Among well-known objects like the Brownian plane or the infinite continuum random tree, we construct two new one-parameter families of metric spaces that appear as scaling limits: the Brownian half-plane with skewness parameter $θ$ and the infinite-volume Brownian disk of perimeter $σ$. We also obtain various coupling and limit results clarifying the relation between these objects.
