refimprove date May 2010 In mathematics and computer science , two Set mathematics sets are said to be disjoint if they have no element mathematics element in common. For example, 1, 2, 3 and 4, 5, 6 are disjoint sets. Explanation Formally, two sets A and B are disjoint if their intersection set theory intersection is the empty set , i.e. if math A cap B varnothing. , math This definition extends to any collection of sets. A collection of sets is pairwise disjoint or mutually disjoint if, given any two sets in the collection, those two sets are disjoint. Formally, let I be an index set , and for each i in I , let A sub i sub be a set. Then the family of sets A sub i sub i I is pairwise disjoint if for any i and j in I with i j , math A i cap A j varnothing. , math For example, the collection of sets 1 , 2 , 3 , ... is pairwise disjoint. If A sub i sub is a pairwise disjoint collection containing at least two sets , then clearly its intersection is empty math bigcap i in I A i varnothing. , math However, the converse is not true the intersection of the collection 1, 2 , 2, 3 , 3, 1 is empty, but the collection is not pairwise disjoint. In fact, there are no two disjoint sets in this collection. A partition of a set X is any collection of non empty subsets A sub i sub i I of X such that A sub i sub are pairwise disjoint and math bigcup i in I A i X. , math References MathWorld title Disjoint Sets urlname DisjointSets See also Almost disjoint sets Connectedness Disjoint union Disjoint set data structure DEFAULTSORT Disjoint Sets Category Basic concepts in set theory Category Set families ca Conjunts disjunts cs Disjunktn mno iny da Disjunkt matematik de Disjunkt et hisosata hulgad es Conjuntos disjuntos eo Disaj aroj fr Ensembles disjoints ko is Sundurl g mengi it Disgiunzione he ja nn Disjunkt nl Disjuncte verzamelingen no Disjunkt pl Zbiory roz czne pt Conjuntos disjuntos sl Disjunktni mno ici fi Erilliset joukot uk vi C c ... more details

That is, for any math A,B in mathcal R math , math A cap B in mathcal R math math A triangle B in mathcal R math where math triangle math represents the symmetric difference math A Delta B A backslash B cup B backslash A . math A ring of sets forms an algebraic ring mathematics ring possibly without unit under these two operations. Intersection distributes over symmetric difference math A cap B triangle C A cap B triangle A cap C math The empty set is the identity element for math triangle math , and the union of all the sets, if it is in the ring, is the identity element for math cap math , making it a unit ring .

In topology and related branches of mathematics , separated sets are pairs of subset s of a given topological space that are related to each other in a certain way. The notion of when two sets are separated or not is important both to the notion of connected space s and their connected components as well as to the separation axiom s for topological spaces. Separated sets should not be confused with separated space s defined below , which are somewhat related but different. Separable space s are again a completely different topological concept. Definitions There are various ways in which two subsets of a topological space X can be considered to be separated. A and B are disjoint if their intersection set theory intersection is the empty set . This property has nothing to do with topology as such, but only naive set theory set theory we include it here because it is the weakest in the sequence of different notions.

unsolved mathematics If any two sets in some family of sets have a union that also belongs to the family, must some element belong to at least half of the sets in the family? In combinatorial mathematics , the union closed sets conjecture is an elementary problem, posed by P ter Frankl in 1979 and still open. A family of sets is said to be union closed if the union of any two sets from the family remains in the family. The conjecture states that for any finite union closed family of finite sets, other than the family consisting only of the empty set , there exists an element that belongs to at least half of the sets in the family. Equivalent forms If F is a union closed family of sets, the family of complement set s to sets in F is closed under intersection, and an element that belongs to at least half of the sets of F belongs to at most half of the complement sets.
