Regular intersecting families

Abstract

We call a family of sets intersecting, if any two sets in the family intersect. In this paper we investigate intersecting families F of k-element subsets of [n] := {1, ..., n}, such that every element of [n] lies in the same (or approximately the same) number of members of.F. In particular, we show that we can guarantee vertical bar vertical bar = o(((n-1)(k-1))) if and only if k = o(n). (C) 2019 Published by Elsevier B.V
