We prove a vector space analog of a version of the Kruskal-Katona theorem due to Lov´asz. We apply this result to extend Frankl’s theorem on r-wise intersecting families to vec...

Let Sn denote the symmetric group on [n] = {1, . . . , n}. A family I ⊆ Sn is intersecting if any two elements of I have at least one common entry. It is known that the only int...

We show that the average size of subsets of [n] forming an intersecting Sperner family of cardinality not less than (n-1 k-1 ) is at least k provided that k 6 n=2
