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…
