Exact solution of three-point functions in critical loop models

Morris Ang, Gefei Cai, Jesper Lykke Jacobsen +4

We propose an exact formula for three-point functions on the sphere in critical loop models with primary fields characterized by legs and a parameter \(s\) that de…

Boundary four-point connectivities of conformal loop ensembles

Gefei Cai

We derive the boundary four-point Green's functions for conformal loop ensembles (CLE) with . Specializing to and , we establish the exact formulas for the…

Backbone probability of planar Brownian motion

Gefei Cai, Zhuoyan Xie

Motivated by critical planar percolation, we investigate a ``backbone'' event of planar Brownian motion, i.e.~the existence of two disjoint subpaths on the Brownian trajectory conn…

Three-point connectivity constant for -state Potts spin clusters

Gefei Cai, Haoyu Liu, Baojun Wu +1

Recently, Ang--Cai--Sun--Wu (2024) determined the three-point connectivity constant for two-dimensional critical percolation, confirming a prediction of Delfino and Viti (2010). In…

Disconnection probability of Brownian motion on an annulus

Gefei Cai, Xuesong Fu, Xin Sun +1

We derive an exact formula for the probability that a Brownian path on an annulus does not disconnect the two boundary components of the annulus. The leading asymptotic behavior of…

Uniqueness of generalized conformal restriction measures and Malliavin-Kontsevich-Suhov measures for

Gefei Cai, Yifan Gao

In this paper, we present a unified approach to establish the uniqueness of generalized conformal restriction measures with central charge in both chordal and radial…
