DIAGRAMS OF AN ABELIAN GROUP
In this paper, we characterize quadratic number fields possessing unique factorization in terms of the power cancellation property of torsion-free rank-two abelian groups, in terms of Ī£-unique decomposition, in terms of a pair of point set topological properties of EilenbergāMac Lane spaces, and in terms of the sequence of rational ā¦
