For $d\\geq3$, two independent copies of such forests, pointing in opposite directions, can be pruned so as to become disjoint. From this, we construct in $d\\geq3$ a stationary, polynomially mixing and uniformly elliptic environment of nearest-neighbor transition probabilities on $\\mathbb{Z}^d$, for which the corresponding random walk disobeys a certain zero--one law for directional transience.", "revisions": [ { "version": "v2", "updated": "2006-06-28T13:51:53.000Z" } ], "analyses": { "subjects": [ "60K37", "05C80", "82D30" ], "keywords": [ "shortest spanning trees", "random environments", "counterexample", "nearest-neighbor transition probabilities", "corresponding random walk disobeys" ], "tags": [ "journal article" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2005math......1533B" } } }
