Pemantle proved that the USF consists a.s. of a single tree if and only if d <= 4. We prove that any two components of the USF in Z^d are adjacent a.s. if 5 <= d <= 8, but not if d >= 9. More generally, let N(x,y) be the minimum number of edges outside the USF in a path joining x and y in Z^d. Then a.s. max{N(x,y) : x,y in Z^d} is the integer part of (d-1)/4. The notion of stochastic dimension for random relations in the lattice is introduced and used in the proof.", "revisions": [ { "version": "v3", "updated": "2003-02-13T17:43:06.000Z" } ], "analyses": { "subjects": [ "60K35", "60J15" ], "keywords": [ "uniform spanning forest", "transitions", "weak limit", "single tree", "stochastic dimension" ], "tags": [ "journal article" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable", "inspire": 580928, "adsabs": "2001math......7140B" } } }
