متن کاملTriangulated Categories and Stable Model Categories
X id → X → 0→ · For any morphism u : X → Y , there is an object Z (called a mapping cone of the morphism u) fitting into a distinguished triangle X u − → Y → Z → · Any triangle isomorphic to a distinguished triangle is distinguished. This means that if X u − → Y v − → Z w −→ X[1] is a distinguished triangle, and f : X → X, g : Y → Y , and h : Z → Z are isomorphisms, then X′ gu f −1 −−−−→ Y ′ hv...
متن کاملFrom Partial Model Categories to ∞-categories
In this article we study the problem of extracting an ∞-category from a relative category. We introduce partial model categories, which are relative categories that satisfy mild versions of the axioms of a model category. Since these axioms involve only the weak equivalences, they are general enough to include the vast majority of the relative categories one encounters in practice. We show that...
متن کاملLocalizations in Triangulated Categories and Model Categories
Recall that for a triangulated category T , a Bousfield localization is an exact functor L : T → T which is coaugmented (there is a natural transformation Id → L; sometimes L is referred to as a pointed endofunctor) and idempotent (there is a natural isomorphism Lη = ηL : L → LL). The kernel ker(L) is the collection of objects X such that LX = 0. If T is closed under coproducts, it’s a localizi...
متن کاملQuillen Model Categories
We provide a brief description of the mathematics that led to Daniel Quillen’s introduction of model categories, a summary of his seminal work “Homotopical algebra”, and a brief description of some of the developments in the field since.
