Transfer of abelian model structures to equivariant categories and homotopy squares
Zhenxing Di, Liping Li, Li Liang +2
Let be a finite group acting on a Grothendieck category with enough projectives, such that is invertible in . We prove a general lifting theore…

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…

Representations of generalized linear Reedy categories and abelian model structures
Zhenxing Di, Liping Li, Li Liang
In this paper we consider representations of generalized -linear Reedy categories , a common generalization of -linear Reedy categories introduced by…
