The extremal process of two-speed branching random walk
Lianghui Luo
We consider a two-speed branching random walk, which consists of two macroscopic stages with different reproduction laws. We prove that the centered maximum converges in law to a G…

Precise upper deviation estimates for the maximum of a branching random walk
Lianghui Luo
We consider the precise upper large deviations estimates for the maximal displacement of a branching random walk. In addition, we obtain a description of the extremal process of th…
