Volume growth and heat kernel estimates for the continuum random tree

Abstract

In this article, we prove global and local (point-wise) volume and heat kernel bounds for the continuum random tree. We demonstrate that there are almost-surely logarithmic global fluctuations and log-logarithmic local fluctuations in the volume of balls of radius rr about the leading order polynomial term as r0r\to0. We also show that the on-diagonal part of the heat kernel exhibits corresponding global and local fluctuations as t0t\to0 almost-surely. Finally, we prove that this quenched (almost-sure) behaviour contrasts with the local annealed (averaged over all realisations of the tree) volume and heat kernel behaviour, which is smooth.
