Locally Type FP n and n-Coherent Categories

D Bravo, J Gillespie, MA Pérez - Applied Categorical Structures, 2023 - Springer
We study finiteness conditions in Grothendieck categories by introducing the concepts of
objects of type FP n and studying their closure properties with respect to short exact …

Locally type and -coherent categories

D Bravo, J Gillespie, MA Pérez - arXiv preprint arXiv:1908.10987, 2019 - arxiv.org
We study finiteness conditions in Grothendieck categories by introducing the concepts of
objects of type $\text {FP} _n $ and studying their closure properties with respect to short …

Torsion and torsion-free classes from objects of finite type in Grothendieck categories

D Bravo, S Odabaşı, CE Parra, MA Pérez - Journal of Algebra, 2022 - Elsevier
In an arbitrary Grothendieck category, we find necessary and sufficient conditions for the
class of FP n-injective objects to be a torsion class. By doing so, we propose a notion of n …

Covers and envelopes in Grothendieck categories: flat covers of complexes with applications

ST Aldrich, EE Enochs, JRG Rozas, L Oyonarte - Journal of Algebra, 2001 - Elsevier
In the general setting of Grothendieck categories with enough projectives, we prove
theorems that make possible to restrict the study of the problem of the existence of F-covers …

Higher dualizability and singly-generated Grothendieck categories

A Chirvasitu - Applied Categorical Structures, 2022 - Springer
Let k be a field. We show that locally presentable, k-linear categories CC dualizable in the
sense that the identity functor can be recovered as ∐ _i x_i ⊗ f_i∐ ixi⊗ fi for objects x_i ∈ C …

Models for homotopy categories of injectives and Gorenstein injectives

J Gillespie - Communications in Algebra, 2017 - Taylor & Francis
ABSTRACT A natural generalization of locally noetherian and locally coherent categories
leads us to define locally type FP∞ categories. They include not just all categories of …

[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 …

[HTML][HTML] Covers, envelopes, and cotorsion theories in locally presentable abelian categories and contramodule categories

L Positselski, J Rosický - Journal of Algebra, 2017 - Elsevier
We prove general results about completeness of cotorsion theories and existence of covers
and envelopes in locally presentable abelian categories, extending the well-established …

On locally coherent hearts

M Saorín - Pacific Journal of Mathematics, 2017 - msp.org
Let G be a locally coherent Grothendieck category. We show that, under particular
conditions, if a t-structure τ in the unbounded derived category D (G) restricts to the bounded …

On the local cohomology and support for triangulated categories

J Asadollahi, S Salarian, R Sazeedeh - 2011 - projecteuclid.org
Recently a notion of support and a construction of local cohomology functors for [TR5]
compactly generated triangulated categories were introduced and studied by Benson …
