Scaling limit of critical percolation clusters on hyperbolic random half-planar triangulations and the associated random walks (2311.11993v1)

Abstract: We show that the Gromov-Hausdorff-Prohorov scaling limit of a critical percolation cluster on a random hyperbolic triangulation of the half-plane is the Brownian continuum random tree. As a corollary, we obtain that a simple random walk on the critical cluster rescales to Brownian motion on the continuum random tree.
