Title
A note on G-intersecting families
Abstract
Consider a graph G and a k-uniform hypergraph H on common vertex set [n]. We say that H is G-intersecting if for every pair of edges in X,Y ∈ H there are vertices x ∈ X and y ∈ Y such that x = y or x and y are joined by an edge in G. This notion was introduced by Bohman, Frieze, Ruszinkó and Thoma who proved a natural generalization of the Erdös-Ko-Rado Theorem for G-intersecting k-uniform hypergraphs for G sparse and k = O(n1/4). In this note, we extend this result to k = O(√n).
