Balanced pairs of Cartan-Eilenberg complexes over virtually Gorenstein rings
Sergio Estrada, Alina Iacob, Yucheng Wang
Let R be a ring and let Ch(R) be the category of complexes of left R-modules. We consider the C-E (Cartan-Eilenberg) exact structure on Ch(R) and show that it is an efficient exact…
One-sided Gorenstein rings
Lars Winther Christensen, Sergio Estrada, Li Liang +2
Distinctive characteristics of Iwanaga--Gorenstein rings are typically understood through their intrinsic symmetry. We show that several of those that pertain to the Gorenstein glo…
K-flatness in Grothendieck categories: Application to quasi-coherent sheaves
Sergio Estrada, James Gillespie, Sinem Odabaşı
Let be any closed symmetric monoidal Grothendieck category. We show that K-flat covers exist universally in the category of chain complexes and that the Ver…
Gorenstein projective precovers and finitely presented modules
Sergio Estrada, Alina Iacob
The existence of the Gorenstein projective precovers over arbitrary rings is an open question. It is known that if the ring has finite Gorenstein global dimension, then every modul…
Five theorems on Gorenstein global dimensions
Lars Winther Christensen, Sergio Estrada, Peder Thompson
We expand on two existing characterizations of rings of Gorenstein (weak) global dimension zero and give two new characterizations of rings of finite Gorenstein (weak) global dimen…
Quillen equivalences inducing Grothendieck duality for unbounded chain complexes of sheaves
Sergio Estrada, James Gillespie
Let be a semiseparated Noetherian scheme with a dualizing complex . We lift some well-known triangulated equivalences associated with Grothendieck duality to Quille…
