How to construct Gorenstein projective modules relative to complete duality pairs over Morita rings
Yajun Ma, Jiafeng Lü, Huanhuan Li +1
Let be a Morita ring with .We first study how to construct (comple…
A new characterization of silting subcategories in the stable category of a Frobenius extriangulated category
Yajun Ma, Nanqing Ding, Yafeng Zhang +1
We give a new characterization of silting subcategories in the stable category of a Frobenius extriangulated category, generalizing the result of Di et al. (J. Algebra 525 (2019) 4…
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…
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…
On Cotorsion pairs of chain complexes
Gang Yang, Ruijuan Du
In the paper we first construct a new cotorsion pair, in the category of chain complexes, from two given cotorsion pairs in the category of modules, and then we consider completene…
Stable homology over associative rings
Olgur Celikbas, Lars Winther Christensen, Li Liang +1
We analyze stable homology over associative rings and obtain results over Artin algebras and commutative noetherian rings. Our study develops similarly for these classes; for simpl…
