Abstract

If a finite abelian group G is a direct product of its subsets such that G = A₁···A_i···A_n, G is said to have the Hajos-n-proprty if it follows that one of these subsets, say A_i is periodic, meaning that there exists a nonidentity element g in G such that gA_i = A_i . Using some properties of cyclotomic polynomials, we will show that the cyclic groups of orders p^α and groups of type (p²,q²) and (p^α,p^β) where p and q are distinct primes and α, β integers ≥ 1 have this property.
