Abstract
We study the density X(t, x) of one-dimensional super-Brownian motion and find the asymptotic behaviour of P(0 < X(t,x) ≤ a) as a ↓ 0 as well as the Hausdorff dimension of the boundary of the support of X(t, ·). The answers are in terms of the leading eigenvalue of the Ornstein-Uhlenbeck generator with a particular killing term. This work is motivated in part by questions of pathwise uniqueness for associated stochastic partial differential equations.
