Abstract:
Necessary and sufficient conditions are found under which two completely decomposable torsion-free Abelian groups of rank 2 have isomorphic automorphism groups. An answer is obtained to the question of under what conditions a completely decomposable Abelian group of rank 2 is uniquely determined by its group of automorphisms.
