Let $ R $ be a ring graded by a group $ G $ and $ n\geq1 $ an integer. We introduce the
notion of $ n $-FCP-gr-projective $ R $-modules and by using of special finitely copresented …

Let $ R $ be a ring and $ n $ a non-negative integer. In this paper, we first introduce the
concept of $ n $-super finitely copresented $ R $-modules and via these modules, we give a …

Let $ R $ be a ring, $ n $ be an non-negative integer and $ d $ be a positive integer or $\infty
$. A right $ R $-module $ M $ is called\emph {$(n, d)^* $-projective} if ${\rm Ext}^ 1_R (M …

In this paper, for some hereditary torsion theory (T, F) with associated torsion radical t, the
concepts of t-finitely cogenerated (t-fcg) modules and t-finitely copresented (t-fcp) modules …
