On purity and applications to coderived and singularity categories

J Stovicek - arXiv preprint arXiv:1412.1615, 2014 - arxiv.org
Given a locally coherent Grothendieck category G, we prove that the homotopy category of
complexes of injective objects (also known as the coderived category of G) is compactly …

Derived, coderived, and contraderived categories of locally presentable abelian categories

L Positselski, J Šťovíček - Journal of Pure and Applied Algebra, 2022 - Elsevier
For a locally presentable abelian category B with a projective generator, we construct the
projective derived and contraderived model structures on the category of complexes …

Deconstructibility and the Hill lemma in Grothendieck categories

J Šťovíček - Forum Mathematicum, 2013 - degruyter.com
A full subcategory of a Grothendieck category is called deconstructible if it consists of all
transfinite extensions of some set of objects. This concept provides a handy framework for …

Parametrizing recollement data for triangulated categories

P Nicolás, M Saorín - Journal of Algebra, 2009 - Elsevier
We give a general parametrization of all the recollement data for a triangulated category with
a set of generators. From this we deduce a characterization of when a ℵ0-perfectly …

Dwyer–Kan homotopy theory of enriched categories

F Muro - Journal of Topology, 2015 - academic.oup.com
We construct a model structure on the category of small categories enriched over a
combinatorial closed symmetric monoidal model category satisfying the monoid axiom …

Enriched indexed categories

M Shulman - arXiv preprint arXiv:1212.3914, 2012 - arxiv.org
We develop a theory of categories which are simultaneously (1) indexed over a base
category S with finite products, and (2) enriched over an S-indexed monoidal category V …

[HTML][HTML] Smash product of pointed objects in lextensive categories

A Carboni, G Janelidze - Journal of Pure and Applied Algebra, 2003 - Elsevier
We describe a sufficient condition on a finitely complete and cocomplete lextensive category
X, under which the categorical smash product provides a canonical (symmetric, distributive …

[HTML][HTML] The enriched Grothendieck construction

J Beardsley, LZ Wong - Advances in Mathematics, 2019 - Elsevier
We define and study opfibrations of V-enriched categories when V is an extensive monoidal
category whose unit is terminal and connected. This includes sets, simplicial sets …

Rectification of enriched∞–categories

R Haugseng - Algebraic & Geometric Topology, 2015 - msp.org
We prove a rectification theorem for enriched∞–categories: if V is a nice monoidal model
category, we show that the homotopy theory of∞–categories enriched in V is equivalent to …

[HTML][HTML] Are all localizing subcategories of stable homotopy categories coreflective?

C Casacuberta, JJ Gutiérrez, J Rosický - Advances in Mathematics, 2014 - Elsevier
We prove that, in a triangulated category with combinatorial models, every localizing
subcategory is coreflective and every colocalizing subcategory is reflective if a certain large …
