Step-reinforced random walks and one half

Under suitable moment assumptions, we show that the step-reinforced random walk exhibits a phase transition between recurrence and transience in dimensions one and two, while remaining transient for all parameters in dimensions three and higher. Moreover, we identify the critical parameter 1/2 which is uniform for step-reinforced random walks in all dimensions.

Limit sets for branching random walks on relatively hyperbolic groups
AbstractBranching random walks (BRW) on groups consist of two independent processes on the Cayley graphs: branching and movement. Start with a particle on a favorite location of the graph. According to a given offspring distribution, the particles at the time n split into a random set of particles with mean $r \ge 1$, each of which then moves independently with a fixed step distribution to the ...
