Özet

A right R-module M is called (generalized) Bassian if the existence of an injective homomorphism M → M/N for some submodule N of M implies that N = {0} (N is a direct summand of M). We partially describe relationships between the classes of Bassian and generalized Bassian modules. In particular, we show that generalized Bassian abelian groups are precisely direct sums of Bassian and semisimple abelian groups, which is a positive answer for Conjecture 1.3 in [P. V. Danchev and P. W. Keef, Generalized Bassian and other mixed abelian groups with bounded p-torsion, J. Algebra 663(1) (2025) 1–19].
