In this paper we prove that matching sizes of $(3/2 + o(1)) n$ suffice to guarantee such a rainbow matching, which is asymptotically the same bound as the best known one in case we only aim to find a rainbow matching of size $n-1$. This improves previous results by Aharoni, Charbit and Howard, and Kotlar and Ziv.", "revisions": [ { "version": "v1", "updated": "2015-03-02T08:36:59.000Z" } ], "analyses": { "keywords": [ "rainbow matching", "matchings guaranteeing", "bipartite multigraph contains", "berger states", "conjecture" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable" } } }
