Model structures on the category of Q-shaped modules

Yajun Ma, Peiru Yang

We develop a method for constructing abelian model structures on the category Q,AMod of Q-shaped modules from cotorsion pairs in AMod, where Q is a small preadditive category satis…

Flat models for Q-shaped derived categories via PGF objects

Zhenxing Di, Liping Li, Li Liang +1

We develop a unified approach, based on projectively coresolved Gorenstein flat (PGF) objects, for constructing flat model structures on diagram categories. Specifically, we show t…

Flat model structures and Gorenstein objects in functor categories

Zhenxing Di, Liping Li, Li Liang +1

We construct a flat model structure on the category of additive functors from a small preadditive category satisfying certain conditi…

How to construct Gorenstein projective modules relative to complete duality pairs over Morita rings

Yajun Ma, Jiafeng Lü, Huanhuan Li +1

Let be a Morita ring with .We first study how to construct (comple…

Recollements induced by left Frobenius pairs

Yajun Ma, Dandan Sun, Rongmin Zhu +1

Given a right exact functor from an abelian category into another abelian category, there is an associated abelian category called the comma category of the functor. In this paper,…

Higher Auslander's defect and classifying substructures of n-exangulated categories

Jiangsheng Hu, Yajun Ma, Dongdong Zhang +1

Herschend-Liu-Nakaoka introduced the notion of -exangulated categories. It is not only a higher dimensional analogue of extriangulated categories defined by Nakaoka-Palu, but al…

A new method to construct model structures from left Frobenius pairs in extriangulated categories

Yajun Ma, Haiyu Liu, Yuxian Geng

Extriangulated categories were introduced by Nakaoka and Palu as a simultaneous generalization of exact categories and triangulated categories. In this paper, we first introduce th…

A new characterization of silting subcategories in the stable category of a Frobenius extriangulated category

Yajun Ma, Nanqing Ding, Yafeng Zhang +1

We give a new characterization of silting subcategories in the stable category of a Frobenius extriangulated category, generalizing the result of Di et al. (J. Algebra 525 (2019) 4…
