Gorenstein flat representations of left rooted quivers
Zhenxing Di, Sergio Estrada, Li Liang +1
We study Gorenstein flat objects in the category of representations of a left rooted quiver with values in , the category of all left -modules…
Relative global dimensions and stable homotopy categories
Li Liang, Junpeng Wang
In this paper we study the finiteness of global Gorenstein AC-homological dimensions for rings, and answer the questions posed by Becerril, Mendoza, Pérez and Santiago. As an appli…
A refinement of Gorenstein flat dimension via the flat--cotorsion theory
Lars Winther Christensen, Sergio Estrada, Li Liang +3
We introduce a refinement of the Gorenstein flat dimension for complexes over an associative ring--the Gorenstein flat-cotorsion dimension--and prove that it, unlike the Gorenstein…
Homology theories and Gorenstein dimensions for complexes
Li Liang
In this paper, we first study the Gorenstein projective/flat dimension of complexes of modules. The relation between the Gorenstein projective/flat dimension for complexes and that…
