Noise sensitivity and exceptional times of transience for a simple symmetric random walk in one dimension

Martin Prigent, Matthew I. Roberts

We define a dynamical simple symmetric random walk in one dimension, and show that there almost surely exist exceptional times at which the walk tends to infinity. This is in contr…

Cover time for branching random walks on regular trees

Matthew I. Roberts

Let $T$ be the regular tree in which every vertex has exactly $d \geq 3$ neighbours. Run a branching random walk on $T$ , in which at each time step every particle gives birth to a ra…
