Quenched local limit theorem for a directed random walk on the backbone of a supercritical oriented percolation cluster for
Stein Andreas Bethuelsen, Matthias Birkner, Andrej Depperschmidt +1
In this work we extend the quenched local limit theorem obtained by the authors in [BBDS23]. More precisely, we consider a directed random walk on the backbone of the supercritical…

Pair coalescence times of ancestral lineages of two-dimensional logistic branching random walks
Matthias Birkner, Andrej Depperschmidt, Timo Schlüter
Consider two ancestral lineages sampled from a system of two-dimensional branching random walks with logistic regulation in the stationary regime. We study the asymptotics of their…

Quenched CLT for ancestral lineages of logistic branching random walks
Matthias Birkner, Andrej Depperschmidt, Timo Schlüter
We consider random walks in dynamic random environments which arise naturally as spatial embeddings of ancestral lineages in spatial locally regulated population models. In particu…
