$r$ ICE-closed subcategories induced by the morphism category of projective modules

Rasool Hafezi, Alireza Nasr-Isfahani, Jiaqun Wei

Let $Λ$ be an Artin $R$ -algebra, and ${\rm proj}\mbox{-}Λ$ denotes the category of all finitely generated projective $Λ$ -modules. Define $\CP(Λ) := {\rm Mor}({\rm proj}\mbox{-}Λ)$.…

A bijection between support $τ$ -tilting subcategories and $τ$ -cotorsion pairs in extriangulated categories

Zhiwei Zhu, Jiaqun Wei

Let $C$ be an extriangulated category with enough projectives and injectives. We give a new definition of tilting subcategories of $C$ and prove it coincides wi…
