Abstract:
The object of this paper is to prove Theorem. For a ring $R$ the following are equivalent: (i) Every cyclic right $R$-module is injective or projective. (ii) $R = S \oplus T$ where $S$ is semisimple artinian and $T$ is a simple right semihereditary right Γre-domain whose every proper cyclic right module is injective.References
