More precisely, vertical edges between neighbouring vertices of $\\mathbb{Z}^2$ can be traversed in both directions (they are undirected) while horizontal edges are one-way. The horizontal orientation is prescribed by a random perturbation of a periodic function, the perturbation probability decays according to a power law in the absolute value of the ordinate. We study the type of the simple random walk, i.e.\\ its being recurrent or transient, and show that there exists a critical value of the decay power, above which the walk is almost surely recurrent and below which is almost surely transient.", "revisions": [ { "version": "v2", "updated": "2014-01-30T16:37:00.000Z" } ], "analyses": { "subjects": [ "60J10", "60K20" ], "keywords": [ "simple random walk", "randomly directed regular lattices", "type transition", "perturbation probability decays", "decay power" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2012arXiv1204.5297C" } } }
