The boxicity of any graph $G$, box(G) is the minimum positive integer b such that G can be represented as the intersection graph of axis parallel b-dimensional boxes. A b-dimensional cube is a Cartesian product $R_1 \\times R_2\\times ... \\times R_b$, where each $R_i$ (for $1 \\leq i \\leq b$) is a closed interval of the form [$a_i$,$a_i$+1] on the real line. When the boxes are restricted to be axis-parallel cubes in b-dimension, the minimum dimension b required to represent the graph is called the cubicity of the graph (denoted by cub(G)). In this paper we prove that $cub(G)\\leq \\lceil \\log n \\rceil \\boxi(G)$} where n is the number of vertices in the graph. This upper bound is tight.", "revisions": [ { "version": "v1", "updated": "2006-05-17T16:33:36.000Z" } ], "analyses": { "subjects": [ "05C62" ], "keywords": [ "upper bound", "real line", "axis parallel b-dimensional boxes", "cartesian product", "closed interval" ], "note": { "typesetting": "TeX", "pages": 6, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2006math......5486C" } } }
