Abstract

We consider a branching random walk on R\mathbb{R} with a stationary and ergodic environment ξ=(ξn)\xi=(\xi_n) indexed by time nNn\in\mathbb{N}. Let ZnZ_n be the counting measure of particles of generation nn. For the case where the corresponding branching process {Zn(R)}\{Z_n(\mathbb{R})\} (nN) (n\in\mathbb{N}) is supercritical, we establish large deviation principles, central limit theorems and a local limit theorem for the sequence of counting measures {Zn}\{Z_n\}, and prove that the position RnR_n (resp. LnL_n) of rightmost (resp. leftmost) particles of generation nn satisfies a law of large numbers.
