Abstract
Neat subgroups of abelian groups have been generalized to modules in essentially two different ways (corresponding to (a) and (b) in the Introduction); they are in general inequivalent, none implies the other. Here we consider relations between the two versions in the commutative case, and characterize the integral domains in which they coincide: these are the domains whose maximal ideals are invertible.
