Hajós' theorem and the partition lemmaSándor SzabóDepartment of Mathematics, University of Bahrain, P. O. Box 32038, State of BahrainAbstract: If a finite abelian group is a direct product of cyclic subsets, then at least one of the factors must be a subgroup. This result is due to G. Hajós. The purpose of this paper is to show that Hajós' theorem can be proved using the so-called partition lemma. Keywords: factorization of finite abelian groups, Hajós-Rédei theory Classification (MSC2000): 20K01 52C22; 52C22 Full text of the article:
