A new category equivalence is proved in this paper, involving the two distinct categories of
modules, the covariant and the contravariant, respectively, released by Higgins and …

In this article we are examining extensions and some basic diagrammatic properties of
modules, in both cases from a new," virtual" point of view. As natural background for …

Departing from a general definition of injectivity of modules with respect to suitable algebraic
classes of morphisms, we establish conditions under which two modules are isomorphic …

By a well known theorem of K. Morita, any equivalence between full module categories over
rings R and S, are given by a bimodule RPS, such that RP is a finitely generated projective …

In a recent paper, Menini and Orsatti obtained a theorem ([4], Representation Theorem 3.1)
between categories of modules which extends Fuller's theorem ([1], Theorem 1.1) to a more …

For any left R-module P with endomorphism ring S, the adjoint pair of functors P⊗ S− and
HomR (P,−) induce an equivalence between the categories of P-static R-modules and P …

In this paper we expose some recent results (see References) on equivalences between
categories of modules. Let A e R be two rings, DA and GR subcategories of Mod-A and Mod …

We give a characterisation of those local not necessary commutative rings, for which the
category of projective modules admits a triangulation with the identity as translation functor …

For modules over a finite-dimensional algebra, there is a canonical one-to-one
correspondence between the projective indecomposable modules and the simple modules …
