Auslander conditions and tilting-like cotorsion pairs

Jian Wang, Yunxia Li, Jinyong Wu +1

We study homological behavior of modules satisfying the Auslander condition. Assume that $A C$ is the class of left $R$ -modules satisfying the Auslander condition. It is p…

How to construct Gorenstein projective modules relative to complete duality pairs over Morita rings

Yajun Ma, Jiafeng Lü, Huanhuan Li +1

Let $Δ = (A_{B} M_{A}_{A} N_{B} B)$ be a Morita ring with $M \otimes_{A} N = 0 = N \otimes_{B} M$ .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…

When the Schur functor induces a triangle-equivalence between Gorenstein defect categories

Huanhuan Li, Jiangsheng Hu, Yuefei Zheng

Let $R$ be an Artin algebra and $e$ an idempotent of $R$ . Assume that $Tor_{i}^{e R e} (R e, G) = 0$ for any $G \in GProj e R e$ and $i$ sufficiently large. Necessary and sufficient…

Gorenstein projective modules and recollements over triangular matrix rings

Huanhuan Li, Yuefei Zheng, Jiangsheng Hu +1

Let $T = (R M 0 S)$ be a triangular matrix ring with $R$ and $S$ rings and $_{R} M_{S}$ an $R$ - $S$ -bimodule. We describe Gorenstein project…
