刘维量子引力度规简介

Introduction to the Liouville quantum gravity metric

Jian Ding, Julien Dubedat, Ewain Gwynne

摘要:

刘维尔量子引力(Liouville quantum gravity,LQG)是20世纪80年代首次出现在物理学文献中的一类单参数随机分形表面模型。最近的工作已经建立了一个度量(距离函数)的LQG表面。我们给出了这个度量的建设的概述,并讨论了它的一些最重要的属性,如测地线和KPZ公式的行为。我们还讨论了一些主要的技术证明声明的LQG度量,给出了它们的使用的例子,并讨论了一些开放的问题。

英文摘要:

Liouville quantum gravity (LQG) is a one-parameter family of models of random fractal surfaces which first appeared in the physics literature in the 1980s. Recent works have constructed a metric (distance function) on an LQG surface. We give an overview of the construction of this metric and discuss some of its most important properties, such as the behavior of geodesics and the KPZ formula. We also discuss some of the main techniques for proving statements about the LQG metric, give examples of their use, and discuss some open problems.
