This function is supposed to be increasing, so that the random walk is attracted by bigger clusters. For $f(t)=e^{\\beta t}$ we prove that there is a phase transition in $\\beta$, i.e., the random walk is subdiffusive for large $\\beta$ and is diffusive for small $\\beta$.", "revisions": [ { "version": "v1", "updated": "2005-07-04T08:56:29.000Z" } ], "analyses": { "subjects": [ "60K37", "60J10" ], "keywords": [ "random walk", "percolation clusters", "phase transition", "bigger clusters", "percolation model" ], "tags": [ "journal article" ], "note": { "typesetting": "TeX", "pages": 13, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2005math......7054P" } } }
