Generally, a partition is a division of a whole into non-overlapping parts. Among the kinds of partitions considered in mathematics are
- partition of a set or an ordered partition of a set,
- partition of a graph,
- partition of an integer,
- partition of an interval,
- partition of unity,
- partition of a matrix; see block matrix, and
- partition of the sum of squares in statistics problems, especially in the analysis of variance,
- quotition and partition, two ways of viewing the operation of division of integers.
