摘要：In this talk, we first give an informal introduction to model structures. We then construct a flat model structure on the category of additive functors from a preadditive category satisfying certain conditions to the module category, whose homotopy category is the Q-shaped derived category introduced by Holm and Jørgensen. Finally, we describe Gorenstein projective objects on the functor category, and hence improve a result by Dell’Ambrogio, Stevenson and Št’ovíček. This is the joint work with Zhenxing Di, Liping Li and Li Liang.
