Asymptotic Radial Speed of the Support of Supercritical Branching and Super-brownian Motion in R

It has long been known that the left-most or right-most particle in a one dimensional dyadic branching Brownian with constant branching rate > 0 has almost sure asymptotic speed p 2, (cf. McKean (1975)). Recently similar results for higher dimensional branching Brownian motions and super-Brownian motion have also been established the weaker sense of… CONTINUE READING
