WebTriangulated categories 3 ring elements f 1,f 2 there existed a unique element ffactoring them as f 1 =fι 1 and f 2 =fι 2. (ii) Let Rbe a ring (associative, with unit element).Then the category R- Mod of all R-modules is additive.Similarly, the category R-mod of finitely generated R-modules is additive.In particular, the categories Ab of abelian groups and Vec … WebWe call a triangulated structure S on C admissible if the canonical projection functor π : Db(H) → C is exact, that is, sends exact triangles to triangles from S. We use the notation CS if we consider C as a triangulated category with triangulated structure S. By Keller [7], C admits an admissible triangulated structure in case
