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…
