Nearly locally presentable categories
L Positselski, J Rosicky - arXiv preprint arXiv:1710.10476, 2017 - arxiv.org
We introduce a new class of categories generalizing locally presentable ones. The
distinction does not manifest in the abelian case and, assuming Vopenka's principle, the …

Exponentiable Grothendieck categories in flat algebraic geometry
I Di Liberti, JR González - Journal of Algebra, 2022 - Elsevier
We introduce and describe the 2-category Grt♭ of Grothendieck categories and flat
morphisms between them. First, we show that the tensor product of locally presentable linear …

Categories of modules, comodules and contramodules over representations
We study and relate categories of modules, comodules and contramodules over a
representation of a small category taking values in (co) algebras, in a manner similar to …

[HTML][HTML] Exactness of direct limits for abelian categories with an injective cogenerator
L Positselski, J Šťovíček - Journal of Pure and Applied Algebra, 2019 - Elsevier
We prove that the exactness of direct limits in an abelian category with products and an
injective cogenerator J is equivalent to a condition on J which is well-known to characterize …

On the tensor product of well generated dg categories
W Lowen, JR González - Journal of Pure and Applied Algebra, 2022 - Elsevier
We endow the homotopy category of well generated (pretriangulated) dg categories with a
tensor product satisfying a universal property. The resulting monoidal structure is symmetric …

Quasi-coherent torsion sheaves, the semiderived category, and the semitensor product: Semi-infinite algebraic geometry of quasi-coherent sheaves on ind-schemes
L Positselski - arXiv preprint arXiv:2104.05517, 2021 - arxiv.org
We construct the semi-infinite tensor structure on the semiderived category of quasi-
coherent torsion sheaves on an ind-scheme endowed with a flat affine morphism into an ind …

On representation categories of -algebras and -coalgebras
A Banerjee, A Naolekar - arXiv preprint arXiv:2112.02707, 2021 - arxiv.org
In this paper, we use the language of monads, comonads and Eilenberg-Moore categories
to describe a categorical framework for $ A_\infty $-algebras and $ A_\infty $-coalgebras, as …
