Exact categories and infinite tilting
W Rump - Communications in Algebra, 2021 - Taylor & Francis
It is proved that any tilting adjunction is completely described by an exact category with a
coherence property and the closure condition that exact sequences are acyclic. The …

Abelian categories arising from cluster tilting subcategories II: quotient functors
Y Liu, P Zhou - Proceedings of the Royal Society of Edinburgh …, 2020 - cambridge.org
In this paper, we consider a kind of ideal quotient of an extriangulated category such that the
ideal is the kernel of a functor from this extriangulated category to an abelian category. We …

Gabriel-Quillen embedding for n-exact categories
R Ebrahimi - Communications in Algebra, 2021 - Taylor & Francis
Our first aim is to provide an analog of the Gabriel-Quillen embedding theorem for n-exact
categories. Also we give an example of an n-exact category that in not an n-cluster tilting …

One-sided exact categories
S Bazzoni, S Crivei - Journal of Pure and Applied Algebra, 2013 - Elsevier
One-sided exact categories appear naturally as instances of Grothendieck pretopologies. In
an additive setting they are given by considering the one-sided part of Keller's axioms …

Projectively generated -abelian categories are -cluster tilting
S Kvamme - arXiv preprint arXiv:1608.07985, 2016 - arxiv.org
Building on work of Jasso, we prove that any projectively generated $ d $-abelian category
is equivalent to a $ d $-cluster tilting subcategory of an abelian category with enough …

On the relation between relative rigid and support tilting
Y Liu, P Zhou - arXiv preprint arXiv:2003.12788, 2020 - arxiv.org
Let B be an extriangulated category with enough projectives and enough injectives. Let C be
a fully rigid subcategory of B which admits a twin cotorsion pair ((C, K),(K, D)). The quotient …

[PDF][PDF] Building pretorsion theories from torsion theories
F Campanini, F Fedele - arXiv preprint arXiv:2310.00316, 2023 - arxiv.org
Pretorsion theories were defined in [11, 12] as “non-pointed torsion theories”, where the zero
object and the zero morphisms are replaced by a class of “trivial objects” and an ideal of …
