The multisubset sum problem for finite abelian groups

Combinatorics 2013-05-15 v1 Number Theory

Abstract

In this note, we give the explicit formula for the number of multisubsets of a finite abelian group GG with any given size such that the sum is equal to a given element gGg\in G. This also gives the number of partitions of gg into a given number of parts over a finite abelian group. An inclusion-exclusion formula for the number of multisubsets of a subset of GG with a given size and a given sum is also obtained.
