Support -tilting posets and Hochschild reconstruction for matrix centralizer algebras
Jiangsheng Hu, Yu-Zhe Liu, Tiwei Zhao
Let be a field and the endomorphism algebra of a finite direct sum of cyclic modules over a finite-dimensional commutative local principal ideal -algebra. We construct a…
Little finitistic dimensions and generalized derived categories
Xiaolei Zhang, Tiwei Zhao, Dingguo Wang
In this paper, we introduced a generalization of the derived category, which is called the -derived category and denoted by $\D_{n}(R)$, of a given ring for each $n\in\mathb…
On the generalizations of global dimensions and singularity categories
Xiaolei Zhang, Tiwei Zhao, Dingguo Wang
For each , we introduce the notion of -singularity category of a given ring , which can be seen as a generalization…
Ideal approximation in -angulated categories
Lingling Tan, Dingguo Wang, Tiwei Zhao
In this paper, we study ideal approximation theory associated to almost -exact structures in extension closed subcategories of -angulated categories. For , an -angula…
Special Precovered Categories of Gorenstein Categories
Tiwei Zhao, Zhaoyong Huang
Let be an abelian category and the subcategory of consisting of projective objects. Let be a full, additive and…
Foxby equivalence relative to -weak injective and -weak flat modules
Zenghui Gao, Tiwei Zhao
Let and be rings and a (faithfully) semidualizing bimodule. We introduce and study -weak flat and -weak injective modules as a generalization of -flat and…
