It is known that a ring R is left Noetherian if and only if every left R-module has an injective
(pre) cover. We show that (1) if R is a right n-coherent ring, then every right R-module has an …

It is known that a ring $ R $ is left Noetherian if and only if every left $ R $-module has an
injective (pre) cover. We show that $(1) $ if $ R $ is a right $ n $-coherent ring, then every …
