Random walk reflected off of infinity, with applications to uniform spanning forests and supercritical Liouville quantum gravity

Ewain Gwynne, Jinwoo Sung

Let be an infinite graph -- not necessarily one-ended -- on which the simple random walk is transient. We define a variant of the continuous-time random walk on $\math…

Dimension lower bounds in random geometry via Lipschitz functions

Manan Bhatia, Ewain Gwynne, Brin Harper

We prove lower bounds for the Hausdorff dimensions of various natural sets associated with the Liouville quantum gravity (LQG) metric. We prove that the set of 3-star points (i.e.,…

CaTherine wheels from trees and Liouville quantum gravity

Danny Calegari, Ewain Gwynne

A CaTherine wheel is a space-filling curve such that for every closed interval , is homeomorphic to a closed disk and is conta…

Percolation of thick points of the log-correlated Gaussian field in high dimensions

Jian Ding, Ewain Gwynne, Zijie Zhuang

We prove that the set of thick points of the log-correlated Gaussian field contains an unbounded path in sufficiently high dimensions. This contrasts with the two-dimensional case,…

Joint scaling limit of a bipolar-oriented triangulation and its dual in the peanosphere sense

Ewain Gwynne, Nina Holden, Xin Sun

Kenyon, Miller, Sheffield, and Wilson (2015) showed how to encode a random bipolar-oriented planar map by means of a random walk with a certain step size distribution. Using this e…

Directed distances in bipolar-oriented triangulations: exact exponents and scaling limits

Jacopo Borga, Ewain Gwynne

We study longest and shortest directed paths in the following natural model of directed random planar maps: the uniform infinite bipolar-oriented triangulation (UIBOT), which is th…
