Abstract
M. Herschend, Y. Liu, H. Nakaoka introduced n-exangulated categories, which are a simultaneous generalization of n-exact categories and (n + 2)-angulated categories. This paper consists of two results on n-exangulated categories: (1) we give an equivalent characterization of axiom (EA2); (2) we provide a new way to construct a closed subfunctor of an n-exangulated category.
