Let $\\alpha(n)$ be the number of rarely visited edges up to time $n$. First, we evaluate $\\mathbb{E}(\\alpha(n))$, show that $n\\to \\mathbb{E}(\\alpha(n))$ is non-decreasing in $n$ and that $\\lim\\limits_{n\\to+\\infty}\\mathbb{E}(\\alpha(n))=2$. Then we study the asymptotic behavior of $\\mathbb{P} (\\alpha(n)>a(\\log n)^2)$ for any $a>0$ and use it to show that there exists a constant $C\\in(0,+\\infty)$ such that $\\limsup\\limits_{n\\to+\\infty}\\frac{\\alpha(n)}{(\\log n)^2}=C$ almost surely.", "revisions": [ { "version": "v1", "updated": "2023-10-25T14:13:45.000Z" } ], "analyses": { "keywords": [ "rarely visited edges", "asymptotic behavior", "simple random walk", "simple symmetric random walk" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable" } } }
