Abstract: We shall consider three results on factoring finite abelian groups by subsets. These are the Hajós', Rédei's and simulation theorems. As L. Fuchs has done in the case of Hajós' theorem we shall obtain families of infinite abelian groups to which these results cannot be extended. We shall then describe classes of infinite abelian groups for which the extension does hold.

Keywords: factorization of finite and infinite abelian groups, Hajós-Rédei theory.

Classification (MSC2000): 20K99; 52C22
