Liouville Brownian Motion


Liouville Brownian motion is the diffusion obtained by changing the clock of planar Brownian motion so that its reference measure is the area measure of Liouville quantum gravity. In conformal coordinates, its energy form under one standard clock convention is

 E(f,g)=1/2intdel f·del gdz,

with the associated operator acting in L^2(mu_h) rather than L^2(dz). Changing this energy normalization changes the diffusion clock.
