Wide subcategories over commutative coherent rings

Tiwei Zhao

In this paper, we mainly prove Hovey's conjecture: for any commutative coherent ring, there is a lattice isomorphism between the lattice of wide subcategories of the category of fi…

From $τ$ -tilting to $τ_{2}$ -tilting via splitting tilting triples

Zhongyuan Wang, Haicheng Zhang, Tiwei Zhao

Let $(A, T, B)$ be a splitting tilting triple. We provide a construction of $τ_{2}$ -tilting $B$ -modules from $τ$ -tilting $A$ -modules. On the other hand, if $A$ is hereditary, by consid…

Support $τ$ -tilting posets and Hochschild reconstruction for matrix centralizer algebras

Jiangsheng Hu, Yu-Zhe Liu, Tiwei Zhao

Let $R$ be a field and $A$ the endomorphism algebra of a finite direct sum of cyclic modules over a finite-dimensional commutative local principal ideal $R$ -algebra. We construct a…

Tilting realizations of derived-equivalent matrix centralizer algebras

Jiangsheng Hu, Xin Ma, Jinbi Zhang +1

Let $A$ be the centralizer algebra of a matrix over an arbitrary field. We solve the fixed-source realization problem for matrix centralizers by proving that the matrix centralizer…
