| Popis | We prove a correspondence between kappa-small fibrations in simplicial presheaf categories equipped with the injective or projective model structure (and left Bousfield localizations thereof) and relatively kappa-compact maps in their underlying quasi-categories for suitably large regular cardinals kappa. We thus obtain a transition result between weakly universal small fibrations in the (type-theoretic) injective Dugger-Rezk-style standard presentations of model toposes and object classifiers in Grothendieck infinity-toposes in the sense of Lurie. |
