Webb27 apr. 2000 · In fact, the injective model structure on the category Ch (A) (see e.g. [Hov01] or [Lur14, Chapter 1]) induces a stable derivator D A . For example, for every quasi-compact, quasi-separated... WebbRecently, Hovey has shown that model category structures naturally arise from small cotorsion pairs over C(Qco(X)), [20]. Since Qco(X) is a Grothendieck cat-egory [8], there is a canonical injective model category structure on C(Qco(X)). However, this structure is not monoidal, that is, compatible with the tensor product on Qco(X), [21, pp. 111-2].

WebbIt is easy to find algebras T ∈ C in a finite tensor category C that naturally come with a lift to a braided commutative algebra T ∈ Z (C) in the Drinfeld center of C.In fact, any finite tensor category has at least two such algebras, namely the monoidal unit I and the canonical end ∫ X ∈ C X ⊗ X ∨.Using the theory of braided operads, we prove that for … WebbModel category. In mathematics, particularly in homotopy theory, a model category is a category with distinguished classes of morphisms ('arrows') called ' weak equivalences ', ' fibrations ' and ' cofibrations ' satisfying certain axioms relating them. These abstract from the category of topological spaces or of chain complexes ( derived ... six shillings and eight pence
