Under some weak conditions on the measure, there is a unique continuous exponential on $E$ naturally associated with $X$. It follows that there exists an $R$-recurrent random walk in the sense of Tweedie on $E$ if and only if $E$ is a recurrent group and there exists a Harris random walk on~$E$.", "revisions": [ { "version": "v1", "updated": "2015-11-09T19:23:30.000Z" } ], "analyses": { "keywords": [ "recurrent random walk", "harris random walk", "invariant measure", "weak conditions", "unique continuous exponential" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2015arXiv151102810S" } } }
