We consider various problems concerning perfect H-packings: Given positive integers n, r, D, we characterise the edge density threshold that ensures a perfect K_r-packing in any graph G on n vertices and with minimum degree at least D. We also give two conjectures concerning degree sequence conditions which force a graph to contain a perfect H-packing. Other related embedding problems are also considered. Indeed, we give a structural result concerning K_r-free graphs that satisfy a certain degree sequence condition.", "revisions": [ { "version": "v2", "updated": "2013-03-08T15:35:43.000Z" } ], "analyses": { "subjects": [ "05C15", "05C35", "05C70" ], "keywords": [ "dense graphs", "perfect packings", "conjectures concerning degree sequence conditions", "problems concerning perfect h-packings", "edge density threshold" ], "note": { "typesetting": "TeX", "pages": 18, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2011arXiv1110.3490B" } } }
