Abstract: An abelian group is -uniserial if its lattice of fully invariant subgroups is totally ordered. Finite rank torsion-free reduced -uniserial groups are characterized. Such a group is a free module over the center of its endomorphism ring, and is a strongly indecomposable discrete valuation ring. Properties similar to those of strongly homogeneous groups are derived.
