Higher homological algebra was introduced by Iyama. It is also known as n-homological algebra where n 2 is a fixed integer, and it deals with n-cluster tilting subcategories of abelian categories. All short exact sequences in such a subcategory are split, but it has nice exact sequences with n + 2 objects. This was recently formalised by Jasso in the theory of n-abelian categories. There is also a derived version of n-homological algebra, formalised by Geiss, Keller, and Oppermann in the theory
