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 the first 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. In the
second talk, I will focus on the properties of the abelian quotients. I will describe the abelian structure,
simple objects, projective objects and injective objects, which provide a new viewpoint to
understand Hilton-Rees Theorem and Auslander-Reiten theory.
