A GENERALIZATION OF HAJOS’ THEOREM
A GENERALIZATION OF HAJOS’ THEOREM
Haj´os’ Theorem states that if a finite abelian group is expressed as a direct product of cyclic subsets, then one of these subsets must be a subgroup. Here factorizations are considered in which one of the factors is not assumed to be cyclic but has certain restrictions on its order placed upon it.
