Complexes of Gorenstein flat modules and Gorenstein cotorsion modules

Z Wang, Z Liu - Communications in Algebra®, 2010 - Taylor & Francis
A complex (C, δ) is called strongly Gorenstein flat if C is exact and Ker δ n is Gorenstein flat
in R-Mod for all n∈ ℤ. Let 𝒮𝒢 stand for the class of strongly Gorenstein flat complexes. We …

By investigating the properties of some special covers and envelopes of modules, we prove
that if R is a Gorenstein ring with the injective envelope of RR flat, then a left R-module is …

Weak Gorenstein cotorsion modules

L Zhao, J Wei, J Hu - Algebra Colloquium, 2018 - World Scientific
Let R be a ring and let 𝒮𝒢ℱ be the class of strongly Gorenstein at right R-modules. We call a

Complete cotorsion pairs in the category of complexes

Z Wang, Z Liu - Turkish Journal of Mathematics, 2013 - journals.tubitak.gov.tr
In this paper, we study completeness of cotorsion pairs in the category of complexes of R-
modules. Let (A, B) be a cotorsion pair in R-Mod. It is shown that the cotorsion pair …
