Localizations of locally presentable categories and exact topologies
Journal of Pure and Applied Algebra, 1990 If A is a locally finitely presentable category, then A is equivalent to Lex \({\mathcal C}\), the category of left exact contravariant functors on the category \({\mathcal C}\) of all finitely presentable objects. This embeds A as an reflective subcategory of the topos, \(Sets^{{\mathcal C}^{op}}\), of presheaves on C. Any localization \({\mathcal L}\)

The ∞$\infty$‐categorical reflection theorem and applications
Journal of Topology, Volume 19, Issue 1, March 2026.Abstract We prove an ∞$\infty$‐categorical version of the reflection theorem of AdÁmek and Rosický [Arch. Math. 25 (1989), no. 1, 89–94]. Namely, that a full subcategory of a presentable ∞$\infty$‐category that is closed under limits and κ$\kappa$‐filtered colimits is a presentable ∞$\infty$‐category.

Health Expectations, Volume 29, Issue 1, February 2026.ABSTRACT Introduction There is a lack of evidence to support UK and international clinical recommendations to delay cervical screening to 12‐weeks postnatal. In previous studies, half of women were out of date for screening by the end of pregnancy and the majority would be more likely to take up cervical screening, if offered at the 6‐week postnatal ...

Quarterly Journal of the Royal Meteorological Society, Volume 152, Issue 774, January 2026 Part A.We exploit the Field Experiment on Sub‐mesoscale Spatio‐Temporal Variability in Lindenberg (FESSTVaL) to compare the performance of an NWP model at sub‐km resolutions with a traditional LES model. Focusing on clear‐sky ABL turbulence (June 14), shallow convective clouds and surface radiation (June 27), and deep convective cold pools (June 29), we find ...

Injective and Projective Model Structures on Enriched Diagram Categories
, 2018 In the enriched setting, the notions of injective and projective model structures on a category of enriched diagrams also make sense. In this paper, we prove the existence of these model structures on enriched diagram categories under local ...

On projectivity in locally presentable categories
Journal of Algebra, 2004 The paper is devoted to some generalizations of projectivity classes, weakly coreflexive categories and cotorsion theories from the category of \(R\)-modules to arbitrary locally presentable categories. If \(\mathcal K\) is a finitely presented category and \(\mathcal A\) is a weakly coreflexive full subcategory of \(\mathcal K\) which is closed under ...

Modeling (∞,1)$(\infty,1)$‐categories with Segal spaces
Bulletin of the London Mathematical Society, Volume 58, Issue 1, January 2026.Abstract In this paper, we construct a model structure for (∞,1)$(\infty,1)$‐categories on the category of simplicial spaces, whose fibrant objects are the Segal spaces. In particular, we show that it is Quillen equivalent to the models of (∞,1)$(\infty,1)$‐categories given by complete Segal spaces and Segal categories.

Rigidification of higher categorical structures
, 2016 Given a limit sketch in which the cones have a finite connected base, we show that a model structure of "up to homotopy" models for this limit sketch in a suitable model category can be transferred to a Quillen equivalent model structure on the category ...

Syntactic characterizations of various classes of locally presentable categories
Journal of Pure and Applied Algebra, 2001 The word `syntactic' in the title of this paper is to be understood in the context of the `Gabriel-Ulmer duality' between small finitely complete categories and locally finitely presentable categories: an example of the former being thought of as the `invariant form' of the (essentially algebraic) theory whose category of models is the corresponding ...
