The minimum cardinality of a resolving set for $G$ is called the metric dimension of $G$, and denoted by $\\beta(G)$. In this paper, we prove that in a connected graph $G$ of order $n$, $\\beta(G)\\leq n-\\gamma(G)$, where $\\gamma(G)$ is the domination number of $G$, and the equality holds if and only if $G$ is a complete graph or a complete bipartite graph $K_{s,t}$, $ s,t\\geq 2$. Then, we obtain new bounds for $\\beta(G)$ in terms of minimum and maximum degree of $G$.", "revisions": [ { "version": "v1", "updated": "2011-12-11T07:12:44.000Z" } ], "analyses": { "keywords": [ "domination number", "metric dimension", "resolving set", "complete bipartite graph", "minimum cardinality" ], "note": { "typesetting": "TeX", "pages": 6, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2011arXiv1112.2326B" } } }
