Duality between injective envelopes and flat covers. (arXiv:2212.02554v1 [math.AC]) http://arxiv.org/abs/2212.02554

Duality between injective envelopes and flat covers

We establish a duality between injective envelopes and flat covers over a commutative Noetherian ring. One case of this duality states that a morphism is an injective envelope, if and only if its Matlis dual is a flat cover. We also show that if we swap injective envelopes and flat covers in this duality, neither implication is true in general.
