Extriangulated categories

WebJan 6, 2024 · Exact categories and extension closed subcategories of an extriangulated category are extriangulated categories, while there exist some other examples of extriangulated categories which are neither exact nor triangulated (see [ 10, 12, 19 ]). WebDec 22, 2024 · Extriangulated category Example Triangulated categories are extriangulated categories. Conversely, any extriangulated category (C,E,s) in which any morphism is both an s-inflation and an s-deflation is a triangulated category. More precisely, a class of all s-triangles satisfies the axiom of triangulated categories.
