A characterization of QF 3 rings

Edgar Andrews Rutter

Vol. 51 (1974), No. 2, 533–536
Abstract

Let R be a ring with minimum condition on left or right ideals. It is shown that R is a QF 3 ring if and only if each finitely generated submodule of the injective hull of R, regarded as a left R-module, is torsionless. The same approach yields a simplified proof that R is quasi-Frobenius if and only if every finitely generated left R-module is torsionless.
