To appear in Random Structures and Algorithms", "categories": [ "math.PR", "math.CO" ], "abstract": "We find conditions for the connectivity of inhomogeneous random graphs with intermediate density. Our results generalize the classical result for G(n, p), when p = c log n/n. We draw n independent points X_i from a general distribution on a separable metric space, and let their indices form the vertex set of a graph. An edge (i,j) is added with probability min(1, \\K(X_i,X_j) log n/n), where \\K \\ge 0 is a fixed kernel. We show that, under reasonably weak assumptions, the connectivity threshold of the model can be determined.", "revisions": [ { "version": "v1", "updated": "2012-10-23T15:03:13.000Z" } ], "analyses": { "subjects": [ "05C80", "60C05" ], "keywords": [ "inhomogeneous random graphs", "log n/n", "connectivity threshold", "independent points", "intermediate density" ], "note": { "typesetting": "TeX", "pages": 13, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2012arXiv1210.6259D" } } }
