Sunflower (mathematics) sunflower lemma, stating that if formula_40 and formula_41 are positive integers then a collection of formula_42 sets of cardinality at most formula_41 contains a sunflower with more than formula_40 sets. The sunflower conjecture is one of several variations of the conjecture of that the factor of formula_45 can be replaced by formula_46 for some constant formula_47. For formula_48 this is now known to be true, with constant formula_49. Sunflower (mathematics) In mathematics, a sunflower or formula_1-system is a collection of sets whose pairwise intersection is constant. This constant intersection is called the kernel of the sunflower. The main research question
