Classification of a class of torsion-free abelian groupsEbru Solak (1) Department of Mathematics, Middle East Technical University, 06531, Ankara, Turkey
The class of almost completely decomposable groups with a critical typeset of type (2, 2) and a regulator quotient of exponent $≤ p^2$ is shown to have exactly 4 near-isomorphism classes of indecomposable groups. Every group of the class is up to near-isomorphism uniquely a direct sum of these four indecomposable groups.
Keywords: Almost completely decomposable group, indecomposable, bounded representation type
