This implies a conjecture of Northshield [34] of similar flavour. For our proof we introduce a general criterion for identifying the Poisson boundary of a stochastic process that might have further applications.", "revisions": [ { "version": "v2", "updated": "2014-01-23T11:45:24.000Z" } ], "analyses": { "subjects": [ "60J50", "60J10", "05C10" ], "keywords": [ "poisson boundary", "graph coincides", "square tiling", "similar flavour", "general criterion" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2013arXiv1301.1506G" } } }
