我们为一系列旨在证明均匀随机平面映射和刘维尔量子引力(LQG)之间强关系的工作奠定了基础。我们的方法依赖于一个双射编码的网站,由某些二维晶格路径的平面三角剖分。我们的双射平行于离散设置的LQG和Schramm-Loewner进化(SLE)的配对树框架介绍了Duplantier,米勒,和谢菲尔德。结合这两个对应关系,使我们能够将统一的站点定位三角测量与 8 / 3 \sqrt {8/3} -LQG和SLE 6 六 .特别地,我们建立了渗流模型的几个泛函到定义为 8 / 3 \sqrt {8/3} -LQG和SLE 6 六 .例如,我们证明了渗流的探索树收敛于分支SLE 6 六 ,并且渗透循环的集合收敛于共形循环系综CLE 6 六 .我们还证明了计数测度在渗流的关键点上的收敛性。我们的结果在其他几个作品中发挥了重要作用,包括一个程序,显示收敛的一致三角剖分的共形结构和工程研究的行为,随机行走的均匀无限平面三角剖分。
We set the foundation for a series of works aimed at proving strong relations between uniform random planar maps and Liouville quantum gravity (LQG). Our method relies on a bijective encoding of site-percolated planar triangulations by certain 2D lattice paths. Our bijection parallels in the discrete setting the mating-of-trees framework of LQG and Schramm-Loewner evolutions (SLE) introduced by Duplantier, Miller, and Sheffield. Combining these two correspondences allows us to relate uniform site-percolated triangulations to 8 / 3 \sqrt {8/3} -LQG and SLE 6 _6 . In particular, we establish the convergence of several functionals of the percolation model to continuous random objects defined in terms of 8 / 3 \sqrt {8/3} -LQG and SLE 6 _6 . For instance, we show that the exploration tree of the percolation converges to a branching SLE 6 _6 , and that the collection of percolation cycles converges to the conformal loop ensemble CLE 6 _6 . We also prove convergence of counting measure on the pivotal points of the percolation. Our results play an essential role in several other works, including a program for showing convergence of the conformal structure of uniform triangulations and works which study the behavior of random walk on the uniform infinite planar triangulation.
