Webb14 apr. 2024 · 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 … WebbThe central question in the theory of random walks on groups is how symmetries of the underlying space give rise to structure and rigidity of the random walks. For example, for nilpotent groups, it follows easily from bounds in Hebisch and Saloff-Coste [ 14 ] that random walks have diffusive behavior, namely that the rate of escape, defined as the … may heritage 2023

It is an object designed to encode the asymptotic behaviour of the random walk, i.e. how trajectories diverge when the number of steps goes to infinity. Despite being called a boundary it is in general a purely measure-theoretical object and ...
