Gabriel-Quillen embedding for $n$-exact categories

Representation Theory 2021-07-02 v3

Abstract

Our first aim is to provide an analog of the Gabriel-Quillen embedding theorem for nn-exact categories. Also we give an example of an nn-exact category that is not an nn-cluster tilting subcategory, and we suggest two possible ways for realizing nn-exact categories as nn-cluster tilting subcategory.
