Model structure arising from one hereditary complete cotorsion pair on extriangulated categories
Jiangsheng Hu, Dongdong Zhang, Pu Zhang +1
Hovey's correspondence between model structures and cotorsion pairs in the setting of abelian categories, has been generalized by Nakaoka-Palu, using two cotorsion pairs, to the se…

Balanced pairs, virtually Gorenstein rings, and cotorsion torsion triples
Sergio Estrada, Jiangsheng Hu, Jan Trlifaj
For any ring , we investigate balanced pairs of classes of modules and their relations to cotorsion triples. We characterize the case when a balanced pair generates a tilting co…

G-dimensions for DG-modules over commutative DG-rings
Jiangsheng Hu, Xiaoyan Yang, Rongmin Zhu
We define and study a notion of G-dimension for DG-modules over a non-positively graded commutative noetherian DG-ring . Some criteria for the finiteness of the G-dimension of a…
