报告题目：Compatible weak factorization systems and flat model structure

时间：4月11日(周五)上午11:00

地点：理工楼503报告厅

报告摘要： In the first part of this talk, we introduce the concept of compatible weak factorization systems in general categories as a counterpart of compatible complete cotorsion pairs in abelian categories. We then describe a method to construct model structures on general categories via two compatible weak factorization systems satisfying certain conditions, and hence, generalize a very useful result by Gillespie for abelian model structures. In the second part of this talk, we 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 Jorgensen. This talk is based on joint works with Liping Li, Li Liang and Yajun Ma.
