We obtain exact almost-sure estimates for the short-time propagation o
f the closed support of (2, d, beta)-superprocesses. Upper estimates a
re derived by solving a certain singular non-linear evolution equation
, whereas lower estimates are obtained by the use of the branching-par
ticle-system approximation.
