The 6 pages that link to Abelian category, each with the reason it gives.

• Homological algebraRelated: Abelian categories provide a common setting for defining complexes and derived functors.

• Hom functorRelated: Its morphism sets are abelian groups, so Hom functors take values in abelian groups.

• Nine lemmaRelated: The Nine lemma holds in abelian categories, where exactness and diagram arguments are well behaved.
