摘要：We investigate abelian  quotients of the categories of short exact sequences. The natural framework to consider the question is via identifying quotients of morphism categories as module categories. In this talk, I will  provide techniques needed for such identifications. These ideas not only can be used to recover the abelian quotients produced by cluster-tilting subcategories of both exact categories and triangulated categories, but also can be used to reach our goal. Then I will introduce some properties of the abelian quotients, which provide a new viewpoint to understanding Hilton-Rees Theorem and Auslander-Reiten theory.
