The so-called Ding-Chen ring is an n-FC ring which is both left and right coherent, and has
both left and right self FP-injective dimensions at most n for some non-negative integer n. In …

The so-called Ding–Chen ring is an n-FC ring which is both left and right coherent, and has

In this article, we introduce and study the Gorenstein cotorsion dimension of modules and
rings. It is shown that this dimension has nice properties when the ring in question is left GF …

Let (A, B) be a cotorsion pair in R-Mod. We define and study notions of A dimension and B
dimension of unbounded complexes, which is given by means of dg-projective resolution …

We prove that, if ℱ is the class of torsion free discrete modules over a profinite group 𝐺, that
is, the class of discrete 𝐺-modules which are torsion free as abelian groups, then (ℱ, ℱ⊥) is …
