We verify the conjecture through a weakening of the hypergraph matching problem. We close the paper by showing that it is NP-complete to decide whether one of the color classes of a bipartite graph can be covered by a $\\mathtt{V}$-free $2$-matching.<\/jats:p>","DOI":"10.37236\/5258","type":"journal-article","created":{"date-parts":[[2020,1,10]],"date-time":"2020-01-10T19:54:05Z","timestamp":1578686045000},"source":"Crossref","is-referenced-by-count":0,"title":["A Note on $\\mathtt{V}$-free 2-matchings"],"prefix":"10.37236","volume":"23","author":[{"given":"Krist\u00f3f","family":"B\u00e9rczi","sequence":"first","affiliation":[]},{"given":"Attila","family":"Bern\u00e1th","sequence":"additional","affiliation":[]},{"given":"M\u00e1t\u00e9","family":"Vizer","sequence":"additional","affiliation":[]}],"member":"23455","published-online":{"date-parts":[[2016,11,25]]},"container-title":["The Electronic Journal of Combinatorics"],"original-title":[],"link":[{"URL":"https:\/\/www.combinatorics.org\/ojs\/index.php\/eljc\/article\/download\/v23i4p27\/pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.combinatorics.org\/ojs\/index.php\/eljc\/article\/download\/v23i4p27\/pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2020,1,17]],"date-time":"2020-01-17T05:10:37Z","timestamp":1579237837000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.combinatorics.org\/ojs\/index.php\/eljc\/article\/view\/v23i4p27"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2016,11,25]]},"references-count":0,"journal-issue":{"issue":"4","published-online":{"date-parts":[[2016,10,14]]}},"URL":"https:\/\/doi.org\/10.37236\/5258","relation":{},"ISSN":["1077-8926"],"issn-type":[{"type":"electronic","value":"1077-8926"}],"subject":[],"published":{"date-parts":[[2016,11,25]]},"article-number":"P4.27"}}
