CORRESPONDENCES OF CLOSED SUBMODULES There is a considerable body of research
dealing with correspondences between the lattice o Page 1 PROCEEDINGS OF THE AMERICAN …

The goal of this work is to develop a functional transfer of properties between a module A
and the category* M* E of right modules over its endomorphism ring* E that is more sensitive …

The notions of relative projectivity and relative injectivity have been extensively developed
during the last years and have proved to be useful in a wide range of situations (see, eg,[1 …

The use of category equivalences for the study of endomorphism rings stems from the Morita
theorem. In a sense, this theorem can be viewed as stating that if P is a finitely generated …

Let R be any ring and N=⊕ i∈ INi be a direct sum of finitely presented left R-modules Ni.
Suppose that D (N) and D (Ni) are the local duals of N and Ni for each i∈ I. We prove that …

In this paper, we first give some characterizations for left QcFcoalgebras, one of them is very
natural since we use the concept of left semi-perfect coalgebras; we also give some new …

Sufficient conditions are given, in module-theoretic terms, for the ideal N (S) of the
endomorphism ring S of a module M consisting of the endomorphisms with essential kernel …

Let A be a strongly group-graded ring. In this paper WC obtain the main results as
following:(1) In A a similar result to Clifford's theorem of the decomposition of induced …
