Multipartition

From HandWiki

In number theory and combinatorics, a multipartition of a positive integer n is a way of writing n as a sum, each element of which is in turn an integer partition.[1] The concept is also found in the theory of Lie algebras.[1][2]

r-component multipartitions

An r-component multipartition of an integer n is an r-tuple of partitions λ(1), ..., λ(r) where each λ(i) is a partition of some ai and the ai sum to n. The number of r-component multipartitions of n is denoted Pr(n). Congruences for the function Pr(n) have been studied by A. O. L. Atkin.[1][3]
