WebJul 28, 2009 · A nice result of Hilton that generalises the Erdős–Ko–Rado (EKR) Theorem says that if and are cross-intersecting sub-families of , then and the bounds are best possible. We give a short proof of a slightly stronger version. For this purpose, we extend Daykin’s proof of the EKR Theorem to obtain the following improvement of the EKR ...

Erdõs–Ko–Rado Theorems: Algebraic Approaches - Cambridge Core
WebThe natural generalization of the EKR Theorem holds for many different objects that have a notion of intersection, and the bulk of this book focuses on algebraic proofs that can be applied to these different objects. The authors introduce tools commonly used in algebraic graph theory and show how these can be used to prove versions of the EKR ...

Let n;r 2N and suppose that n > 2r. If Aˆ[n](r) is an intersecting family with jAj N M + 2, then there exists an x 2[n] such that A= A x. The next result we shall require, due to Friedgut [13], is a quantitative extension of the Hilton–Milner theorem which says that any su ciently large uniform intersecting family must resemble ... golfing for dummies book
