Localisation of locally presentable categories
The localisations of locally finitely presentable categories are characterised in the context of enriched categories in terms of completeness, smallness and limit-colimit commutativity. More precisely: The authors consider categories enriched in a locally finitely presentable closed category V and show that a V-category E is a localisation of a locally

A representability theorem for some huge abelian categories
We define quasi--locally presentable categories as big unions of coreflective subcategories which are locally presentable. Under appropriate hypotheses we prove a representability theorem for exact contravariant functors defined on a quasi--locally ...

Lifting accessible model structures
A Quillen model structure is presented by an interacting pair of weak factorization systems. We prove that in the world of locally presentable categories, any weak factorization system with accessible functorial factorizations can be lifted along either ...

Simplicial presheaves of coalgebras [PDF]
The category of simplicial R-coalgebras over a presheaf of commutative unital rings on a small Grothendieck site is endowed with a left proper, simplicial, cofibrantly generated model category structure where the weak equivalences are the local weak ...

On the tensor product of linear sites and Grothendieck categories
We define a tensor product of linear sites, and a resulting tensor product of Grothendieck categories based upon their representations as categories of linear sheaves.

An embedding theorem for regular Mal'tsev categories
In this paper, we obtain a non-abelian analogue of Lubkin's embedding theorem for abelian categories. Our theorem faithfully embeds any small regular Mal'tsev category $\mathbb{C}$ in an $n$-th power of a particular locally finitely presentable regular ...

Assembly of constructible factorization algebras
Abstract We provide a toolbox of extension, gluing, and assembly techniques for factorization algebras. Using these tools, we fill various gaps in the literature on factorization algebras on stratified manifolds, the main one being that constructible factorization algebras form a sheaf of symmetric monoidal ∞$\infty$‐categories.

Strongly Complete Logics for Coalgebras [PDF]
Coalgebras for a functor model different types of transition systems in a uniform way. This paper focuses on a uniform account of finitary logics for set-based coalgebras.
