Resolutions for a morphism of localizers #
Given a morphism of localizers Φ : LocalizerMorphism W₁ W₂ (i.e. W₁ and W₂ are
morphism properties on categories C₁ and C₂, and we have a functor
Φ.functor : C₁ ⥤ C₂ which sends morphisms in W₁ to morphisms in W₂), we introduce
the notion of right resolutions of objects in C₂: if X₂ : C₂.
A right resolution consists of an object X₁ : C₁ and a morphism
w : X₂ ⟶ Φ.functor.obj X₁ that is in W₂. Then, the typeclass
Φ.HasRightResolutions holds when any X₂ : C₂ has a right resolution.
The type of right resolutions Φ.RightResolution X₂ is endowed with a category
structure when the morphism property W₁ is multiplicative.
Similar definitions are done from left resolutions.
Future works #
- formalize right derivability structures as localizer morphisms admitting right resolutions and forming a Guitart exact square, as it is defined in the paper by Kahn and Maltsiniotis (TODO @joelriou)
- show that if
Cis an abelian category with enough injectives, there is a derivability structure associated to the inclusion of the full subcategory of complexes of injective objects into the bounded below homotopy category ofC(TODO @joelriou) - formalize dual results
