Remarks on random walks on graphs and the Floyd boundary

Research output: Contribution to journalArticlepeer-review


We show that for a uniformly irreducible random walk on a graph, with bounded range, there is a Floyd function for which the random walk converges to its corresponding Floyd boundary. Moreover if we add the assumptions, p (n) (v, w)≤Cρ n, where ρ<1 is the spectral radius, then for any Floyd function f that satisfies ∞ n=1 nf(n)<∞, the Dirichlet problem with respect to the Floyd boundary is solvable.
