KnowraErdős–Ko–Rado theoremLinked fromLinked fromThe 5 pages that link to Erdős–Ko–Rado theorem, each with the reason it gives.All 5Broader topic 1Related 3Compared with 1Paul ErdősBroader topic: It exemplifies Erdős’s work on extremal questions about set systems.Probabilistic methodRelated: Probabilistic arguments illuminate extremal bounds on families of combinatorial objects.Extremal combinatoricsRelated: It is a central extremal result about set families constrained by pairwise intersection.Sperner's theoremCompared with: It adds an intersection constraint, unlike Sperner's incomparability condition.Cameron–Erdős conjectureRelated: It is a contrasting extremal result: it bounds the largest family, not the number of additive-free families.
