The singularity category of an exact category applied to characterize Gorenstein schemes
Lars Winther Christensen, Nanqing Ding, Sergio Estrada +3
We study singularity categories of exact categories with a focus on those associated to a complete hereditary cotorsion pair. As an application we identify a non-affine analogue of…
2-recollements of singualrity categories and Gorenstein defect categories over triangular matrix algebras
Huanhuan Li, Dandan Yang, Yuefei Zheng +1
Let be a triangular matrix algebra with its corner algebras and Artinian and an --bimodule. The 2-recollement structures for singularity categor…
Frobenius functors and Gorenstein projective precovers
Jiangsheng Hu, Huanhuan Li, Jiafeng Lu +1
We establish relations between Gorenstein projective precovers linked by Frobenius functors. This is motivated by an open problem that how to find general classes of rings for whic…
Leavitt path algebras, -algebras and Keller's conjecture for singular Hochschild cohomology
Xiao-Wu Chen, Huanhuan Li, Zhengfang Wang
For a finite quiver without sinks, we establish an isomorphism in the homotopy category of -algebras between the Hochschild cochain complex of…
When the Schur functor induces a triangle-equivalence between Gorenstein defect categories
Huanhuan Li, Jiangsheng Hu, Yuefei Zheng
Let be an Artin algebra and an idempotent of . Assume that for any and sufficiently large. Necessary and sufficient…
