Borg asked<\/a> what happens to the Erd\u0151s-Ko-Rado theorem if we only count sets meeting some fixed set \"X\", and answered the question for \"|X| \geq r\", the size of the sets in the set family. This paper answers the question for \"|X| < r\", provided \"n\", the size of the ground set, is sufficiently large.<\/p>\n

There is a typo in the proof of Theorem 4 in the journal version. The line beginning “By Lemma 9, \"\mathcal F(2, n, G)(X)\" has size polynomial in \"n\" …” should read “By Lemma 9, \"\mathcal F( r, n, G)( X)\" …”. Thanks to Candida Bowtell for spotting this.<\/p>\n","protected":false},"excerpt":{"rendered":"
