Let $G_n=([n],E_n)$ be the complete graph on vertex set $[n]=\\{1,2,\\ldots,n\\}$, and i.i.d. sequence $\\{X_e:e\\in E_n\\}$ be the passage times of edges. Denote by $W_n$ the largest passage time among all self-avoiding paths from 1 to $n$. First, it is proved that $W_n/n$ converges to constant $\\mu$, where $\\mu$ is called the time constant and coincides with the essential supremum of $X_e$. Second, when $\\mu<\\infty$, it is proved that the deviation probability $P(W_n/n\\leq \\mu-x)$ decays as fast as $e^{-\\Theta(n^2)}$, and as a corollary, an upper bound for the variance of $W_n$ is obtained. Finally, when $\\mu=\\infty$, lower and upper bounds for $W_n/n$ are given.", "revisions": [ { "version": "v1", "updated": "2017-11-11T02:04:06.000Z" } ], "analyses": { "keywords": [ "complete graph", "time constant", "passage percolation", "upper bound", "largest passage time" ], "note": { "typesetting": "TeX", "pages": 12, "language": "en", "license": "arXiv", "status": "editable" } } }
