If $k\\geq (\\nu-3)/4$, a graph $G$ is $k\\ 1/2$-extendable if and only if it is $(2k+1)$-factor-critical. We also give examples to show that the two bounds are best possible. Our results are answers to a problem posted by Favaron [3] and Yu [11].", "revisions": [ { "version": "v1", "updated": "2010-11-15T13:47:01.000Z" } ], "analyses": { "subjects": [ "05C70" ], "keywords": [ "equivalence", "factor-criticality", "extendibility", "non-bipartite graph" ], "tags": [ "journal article" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2010arXiv1011.3381Z" } } }
