Abstract
We study the simple random walk on the uniform spanning tree on Z2 . We
obtain estimates for the transition probabilities of the random walk, the distance of the
walk from its starting point after n steps, and exit times of both Euclidean balls and balls
in the intrinsic graph metric. In particular, we prove that the spectral dimension of the
uniform spanning tree on Z2 is 16/13 almost surely.
Obtains fractal dimension, walk dimension, and spectral dimension, which are related by Barlow, Coulhon, and Kumagai 2005.
