This paper provides a positive and a negative result concerning presentations of modules.
The positive result is a characterization of strongly Ž. isomorphic presentations see the …

The purpose of this paper is to study locally pseudo-valuation domains which are
quasinormal domains. In particular, we give some results on locally pseudovaluation …

Let L,,..., L, be submodules of a finitely generated, projective module M over a (commutative)
integral domain R. Is there a decompositionM= Ml@* a* CiJ M,, with each Mi of rank 1, which …

Consider a discrete valuation ring R whose residue field is finite of cardinality at least 3. For
a finite torsion module, we consider transitive subsets O under the action of the …

In this article we give a complete characterization of all locally cyclic modules—and, in
particular, all faithful and all divisible locally cyclic modules—over a valuation ring of …

Our object in this paper is to characterize all the rings which can occur as endomorphism
rings of reduced torsion-free modules over a complete discrete valuation ring. A complete …

This note offers an unusual approach of studying a class of modules inasmuch as it is
investigating a subclass of the category of modules over a valuation domain. This class is far …

The problem of investigating*-modules over valuation rings was proposed to the author by
C. Menini. We recall the definition of*-module, given by D'Este in [3]. Let. R be a ring, RM a …
