Survival of branching random walks in random environment
Nina Gantert, Sebastian Müller, Serguei Popov +1
We study survival of nearest-neighbour branching random walks in random environment (BRWRE) on . A priori there are three different regimes of survival: global surviva…
Asymptotics for the survival probability in a killed branching random walk
Nina Gantert, Yueyun Hu, Zhan Shi
Consider a discrete-time one-dimensional supercritical branching random walk. We study the probability that there exists an infinite ray in the branching random walk that always li…
Survival time of random walk in random environment among soft obstacles
Nina Gantert, Serguei Popov, Marina Vachkovskaia
We consider a Random Walk in Random Environment (RWRE) moving in an i.i.d.\ random field of obstacles. When the particle hits an obstacle, it disappears with a positive probability…
On slowdown and speedup of transient random walks in random environment
Alexander Fribergh, Nina Gantert, Serguei Popov
We consider one-dimensional random walks in random environment which are transient to the right. Our main interest is in the study of the sub-ballistic regime, where at time th…
