Abstract

In this paper we prove the existence of average densities for the support of a super Brownian motion at a fixed time. Our result establishes a dimension-dependent fractal parameter for super-Brownian motion, which enables us to compare the local mass density of the super-Brownian motion at a fixed time with the local mass density of the occupation measure of a standard Brownian motion.
