partition


A partitionMathworldPlanetmathPlanetmath P of a set S is a collectionMathworldPlanetmath of pairwise disjoint nonempty sets such that P=S.

Any partition P of a set S introduces an equivalence relationMathworldPlanetmath on S, where each AP is an equivalence classMathworldPlanetmath. Similarly, given an equivalence relation on S, the collection of distinct equivalence classes is a partition of S.
