We review the basic definitions of derived categories and derived functors. We illustrate them on simple but non trivial examples. Then we explain Happel's theorem which states that each tilting triple yields an equivalence between derived categories. We establish its link with Rickard's theorem which characterizes derived …

WebDec 17, 2024 · 1. There are essentially no limits in the derived category, whether the diagram factors through chain complexes or not. For instance, any monomorphism in any triangulated category must be split. This is a nice exercise from the axioms. All that exists is products and coproducts, almost without exception.

WebThe derived category is a natural framework to define and study derived functors. In the following, let F: A → B be a functor of abelian categories. There are two dual concepts: right derived functors come from left exact functors and are calculated via injective resolutions WebWhat are Herbal products? Herbal products are medicines derived from plants. They are used as supplements to improve health and well being, and may be used for other therapeutic purposes. Herbal products are available as tablets, capsules, powders, extracts, teas and so on.
