Abstract

We introduce n-abelian and n-exact categories, these are analogs of abelian and exact categories from the point of view of higher homological algebra. We show that n-cluster-tilting subcategories of abelian (resp. exact) categories are n-abelian (resp. n-exact). These results allow to construct several examples of n-abelian and n-exact categories. Conversely, we prove that n-abelian categories satisfying certain mild assumptions can be realized as n-cluster-tilting subcategories of abelian categories. In analogy with a classical result of Happel, we show that the stable category of a Frobenius n-exact category has a natural \((n+2)\)-angulated structure in the sense of Geiß–Keller–Oppermann. We give several examples of n-abelian and n-exact categories which have appeared in representation theory, commutative algebra, commutative and non-commutative algebraic geometry.

Notes

  1. One may consider the more general case when \(\Sigma :\mathcal {F}\rightarrow \mathcal {F}\) is an autoequivalence. As mentioned in [21, 2.2 Rmks.], it can be shown that the assumption of \(\Sigma \) being invertible is but a mild sacrifice, cf. [39, Sect. 2].
