A Haj\'os type result on factoring finite abelian groups by subsets II

Comment.Math.Univ.Carolin. 51,1 (2010) 1-8.

Abstract:It is proved that if a finite abelian group is factored into a direct product of lacunary cyclic subsets, then at least one of the factors must be periodic. This result generalizes Haj\'os's factorization theorem.

Keywords: factorization of finite abelian groups, periodic subset, cyclic subset, Haj\'os's theorem
