The SLE Bubble Measure via Conformal Welding of Quantum Surfaces

Da Wu

AI总结:

本文证明SLE气泡测度自然产生于两个Liouville量子引力圆盘的共形焊接,并给出分解公式,进而计算SLE气泡共形半径的矩,并将Liouville共形场论中的体-边界关联函数与量子边界长度和量子面积联系起来。

摘要:

我们证明了Zhan最近构造的SLE气泡测度自然产生于两个Liouville量子引力(LQG)圆盘的共形焊接。该证明依赖于:(1)SLE气泡极限构造的“量子版本”;(2)由Ang、Sun和Yu建立的量子三角形与量子圆盘之间的共形焊接;(3)Ang、Holden和Sun的一致嵌入技术。作为我们证明的副产品,我们得到了SLE气泡测度的一个分解公式。此外,我们提供了共形焊接结果的两个应用。首先,我们计算了在上半平面上以周围i为条件时SLE气泡的共形半径的矩。第二个应用涉及Liouville共形场论(LCFT)中的体-边界关联函数。在概率框架内,我们推导出一个公式,将LCFT中的体-边界关联函数与左右量子边界长度的联合分布以及双点量子圆盘的量子面积联系起来。该关系被Ang、Remy、Sun和Zhu在一项并行工作中用于验证Hosomichi(2001)所预测的物理学中双点体-边界关联函数公式。

英文摘要:

We showed that the SLE bubble measure recently constructed by Zhan arises naturally from the conformal welding of two Liouville quantum gravity (LQG) disks. The proof relies on (1) a "quantum version" of the limiting construction of the SLE bubble, (2) the conformal welding between quantum triangles and quantum disks due to Ang, Sun and Yu, and (3) the uniform embedding techniques of Ang, Holden and Sun. As a by-product of our proof, we obtained a decomposition formula of the SLE bubble measure. Furthermore, we provided two applications of our conformal welding results. First, we computed the moments of the conformal radius of the SLE bubble on the upper half plane conditioning on surrounding i. The second application concerns the bulk-boundary correlation function in the Liouville Conformal Field Theory (LCFT). Within probabilistic frameworks, we derived a formula linking the bulk-boundary correlation function in the LCFT to the joint law of left and right quantum boundary lengths, and the quantum area of the two-pointed quantum disk. This relation is used by Ang, Remy, Sun and Zhu in a concurrent work to verify the formula of two-pointed bulk-boundary correlation function in physics predicted by Hosomichi (2001).
