Branching brownian motion conditioned on large level sets
Xinxin Chen, Heng Ma
We study the precise large deviation probabilities for the sizes of intermediate level sets in branching Brownian motion (BBM). Our conclusions improve a result of Aïdekon, Hu and…

Multifractal spectrum of branching random walks on free groups
Shuwen Lai, Heng Ma, Longmin Wang
Consider a symmetric branching random walk on a free group in the transient regime , where is the mean offspring number and is the reciprocal of the…

Branching random walk conditioned on large martingale limit
Xinxin Chen, Loïc de Raphélis, Heng Ma
We consider a branching random walk in the non-boundary case where the additive martingale converges a.s. and in mean to some non-degenerate limit . We first establ…
