Minimalities and modules over Dedekind-like rings

摘要

We are interested in (right) modules M satisfying the following weak divisibility condition: If R is the underlying ring, then for every r is an element of R either Mr = 0 or Mr = M . Over a commutative ring, this is equivalent to say that M is connected with regular generics. Over arbitrary rings, modules which are "minimal" in several model theoretic senses satisfy this condition. In this article, we investigate modules with this weak divisibility property over Dedekind-like rings and over other related classes of rings.
