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…

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…
