Commutative Algebra 2021-11-04 v1

Abstract

We first introduce and study the notion of semi-regular flat modules, and then show that a ring RR is a strong \Prufer\ ring if and only if every submodule of a semi-regular flat RR-module is semi-regular flat, if and only if every ideal of RR is semi-regular flat, if and only if every RR-module has a surjective semi-regular flat (pre)envelope.
