Green kernel estimates and the full Martin boundary for random walks on lamplighter groups and Diestel-Leader graphs
Sara Brofferio, Wolfgang Woess
We determine the precise asymptotic behaviour (in space) of the Green kernel of simple random walk with drift on the Diestel-Leader graph , where . The latter i…

The Poisson boundary of random rational affinities
Sara Brofferio
The group of affine transformations with rational coefficients acts naturally on the real line, but also on the -adic fields. The aim of this note is to show that, for random wa…
