Preview Abstract
In this paper, by taking the class of all $C 3$ (or $D 3$ ) right $R$ -modules for general envelopes and covers, we characterize a semisimple artinian ring (or a right perfect ring) via $D 3$ -covers (or $D 3$ -envelopes) and a right $V$ -ring (or a right noetherian $V$ -ring) via $C 3$ -covers (or $C 3$ -envelopes). By using isosimple-projective preenvelope, we obtained that if $R$ is a semiperfect right FGF ring (or left coherent ring), then every isosimple right $R$ -module has a projective cover. Moreover, we also characterize semihereditary serial rings (respectively, hereditary artinian serial rings) in terms of epic flat (respectively, projective) envelopes.
