Quillen equivalence for chain homotopy categories induced by balanced pairs

Jiangsheng Hu, Wei Ren, Xiaoyan Yang +1

For a balanced pair $(X, Y)$ in an abelian category, we investigate when the chain homotopy categories $K (X)$ and $K (Y)$ are tria…

Quasi-projective dimensions of complexes over rings

Hongxing Chen, Jiangsheng Hu, Xiaoyan Yang

Quasi-projective dimension of modules over associative rings is generalized in this paper to the one of complexes of modules. Basic properties of this dimension are established, in…

Models for chain homotopy category of relative acyclic complexes

Jiangsheng Hu, Wei Ren, Xiaoyan Yang +1

Let $(X, Y)$ be a balanced pair in an abelian category $A$ . Denote by $K_{E - ac} (X)$ the chain homotopy category…
