2-recollements of singualrity categories and Gorenstein defect categories over triangular matrix algebras

Huanhuan Li, Dandan Yang, Yuefei Zheng +1

Let $T = (A, M, 0, B)$ be a triangular matrix algebra with its corner algebras $A$ and $B$ Artinian and $_{A} M_{B}$ an $A$ - $B$ -bimodule. The 2-recollement structures for singularity categor…

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…
