随机曲面保形焊接下SLE的可积性

Integrability of SLE via conformal welding of random surfaces

Morris Ang, Nina Holden, Xin Sun

摘要:

我们演示了如何从刘维共形域论(LCFT)和刘维量子引力(LQG)的树匹配框架中获得Schramm-Loewner演化(SLE)的可积结果。特别是,我们证明了一个精确的公式的法律的共形导数的一个经典的变体SLE称为$\mathrm{SLE}_κ(ρ_-;ρ_+)$。我们的证明是建立在SLE,LCFT和交配树之间的两个连接。首先,LCFT和匹配树提供了等价但互补的方法来描述自然随机表面LQG。使用一种新的工具,我们称之为均匀嵌入的LQG表面,我们延伸早期的等价结果,允许更少的标记点和更通用的奇点。其次,这些随机曲面的保形焊接产生SLE曲线作为它们的界面。特别是,我们依赖于保形焊接结果证明在我们的同伴文件[AHS 20]。我们的论文是一个程序的重要组成部分证明可积性结果SLE,LCFT,和交配的树基于这两个连接。

英文摘要:

We demonstrate how to obtain integrable results for the Schramm-Loewner evolution (SLE) from Liouville conformal field theory (LCFT) and the mating-of-trees framework for Liouville quantum gravity (LQG). In particular, we prove an exact formula for the law of a conformal derivative of a classical variant of SLE called $\mathrm{SLE}_κ(ρ_-;ρ_+)$. Our proof is built on two connections between SLE, LCFT, and mating-of-trees. Firstly, LCFT and mating-of-trees provide equivalent but complementary methods to describe natural random surfaces in LQG. Using a novel tool that we call the uniform embedding of an LQG surface, we extend earlier equivalence results by allowing fewer marked points and more generic singularities. Secondly, the conformal welding of these random surfaces produces SLE curves as their interfaces. In particular, we rely on the conformal welding results proved in our companion paper [AHS20]. Our paper is an essential part of a program proving integrability results for SLE, LCFT, and mating-of-trees based on these two connections.
