Abstract

Liouville Brownian motion (LBM) is the canonical diffusion process on a Liouville quantum gravity (LQG) surface. In this work, we establish upper and lower bounds for the heat kernel for LBM when γ=8/3\gamma=\sqrt{8/3} in terms of the 8/3\sqrt{8/3}-LQG metric which are sharp up to a polylogarithmic factor in the exponential.
