Gorenstein cohomological dimension and stable categories for groups
Wei Ren
First we study the Gorenstein cohomological dimension of groups over coefficient rings , under changes of groups and rings; a characterization for finiteness…
Frobenius functors, stable equivalences and -theory of Gorenstein projective modules
Wei Ren
Owing to the difference in -theory, an example by Dugger and Shipley implies that the equivalence of stable categories of Gorenstein projective modules should not be a Quillen e…
On pure derived and pure singularity categories
Tianya Cao, Wei Ren
Firstly, we compare the bounded derived categories with respect to the pure-exact and the usual exact structures, and describe bounded derived category by pure-projective modules,…
Quillen equivalence of singular model categories
Wei Ren
Let be a left-Gorenstein ring. We show that there is a Quillen equivalence between singular contraderived model category and singular coderived model category. Consequently, an…
Gorenstein projective and injective dimensions over Frobenius extensions
Wei Ren
Let be a Frobenius extension of rings. We prove that: (1) for any left -module , is Gorenstein projective (injective) if and only if the underlying left…
Gorenstein projective modules and Frobenius extensions
Wei Ren
We prove that for a Frobenius extension, if a module over the extension ring is Gorenstein projective, then its underlying module over the the base ring is Gorenstein projective; t…
Applications of cotorsion triples
Wei Ren
We study homotopy categories of model categories arising from a cotorsion triple, and the equivalences between corresponding stable categories. We characterize homological dimensio…
