Injective model category

WebbIn the category of abelian groups and group homomorphisms, Ab, an injective object is necessarily a divisible group. Assuming the axiom of choice, the notions are equivalent. In the category of (left) modules and module homomorphisms, R - Mod, an injective object is an injective module. Webb26 okt. 2024 · AC-Gorenstein rings and their stable module categories James Gillespie We introduce what is meant by an AC-Gorenstein ring. It is a generalized notion of Gorenstein ring which is compatible with the Gorenstein AC-injective and Gorenstein AC-projective modules of Bravo-Gillespie-Hovey.

Using these results, we describe … 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 …
