On S-(h-)divisible modules and their S-strongly flat covers

Commutative Algebra 2025-09-03 v1

Abstract

It was proved in [3] that every h-divisible modules admits an strongly flat cover over all integral domains; and every divisible module over an integral domain R admits a strongly flat cover if and only if R is a Matlis domain. In this paper, we extend these two results to commutative rings with multiplicative subsets.
