Grothendieck groups in extriangulated categories

B Zhu, X Zhuang - Journal of Algebra, 2021 - Elsevier
Extriangulated categories were introduced by Nakaoka and Palu to give a unification of
properties in exact categories and triangulated categories. We consider in this article the …

[PDF][PDF] Cluster-tilting subcategories in extriangulated categories

P Zhou, B Zhu - Theory Appl. Categ, 2019 - 198.164.44.141
Let (C, E, s) be an extriangulated category. We show that certain quotient categories of
extriangulated categories are equivalent to module categories by some restriction of functor …

n-exangulated categories (II): Constructions from n-cluster tilting subcategories

M Herschend, Y Liu, H Nakaoka - Journal of Algebra, 2022 - Elsevier
Abstract In n-Exangulated Categories (I), we introduced the notion of n-exangulated
categories for each positive integer n. It is not only a higher dimensional analogue of …

[HTML][HTML] Triangulated quotient categories revisited

P Zhou, B Zhu - Journal of Algebra, 2018 - Elsevier
Extriangulated categories were introduced by Nakaoka and Palu by extracting the
similarities between exact categories and triangulated categories. A notion of mutation of …

Grothendieck groups of triangulated categories via cluster tilting subcategories

F Fedele - Nagoya Mathematical Journal, 2021 - cambridge.org
Let $ k $ be a field, and let ${\mathcal {C}} $ be a $ k $-linear, Hom-finite triangulated
category with split idempotents. In this paper, we show that under suitable circumstances …

The Grothendieck Group of an n-exangulated Category

J Haugland - Applied Categorical Structures, 2021 - Springer
We define the Grothendieck group of an n-exangulated category. For n odd, we show that
this group shares many properties with the Grothendieck group of an exact or a triangulated …

Relations for the Grothendieck groups of triangulated categories

J Xiao, B Zhu - Journal of Algebra, 2002 - Elsevier
A class of triangulated categories with a finiteness condition is singled out. These
triangulated categories have Auslander–Reiten triangles. It is proved that the relations of the …

An assortment of properties of silting subcategories of extriangulated categories

T Adachi, M Tsukamoto - arXiv preprint arXiv:2303.08125, 2023 - arxiv.org
Extriangulated categories give a simultaneous generalization of triangulated categories and
exact categories. In this paper, we study silting subcategories of an extriangulated category …

Abelian categories arising from cluster tilting subcategories

Y Liu, P Zhou - Applied Categorical Structures, 2020 - Springer
For a triangulated category TT, if CC is a cluster-tilting subcategory of TT, then the factor
category T/CT/C is an abelian category. Under certain conditions, the converse also holds …

[HTML][HTML] A resolution theorem for extriangulated categories with applications to the index

Y Ogawa, A Shah - Journal of Algebra, 2024 - Elsevier
Abstract Quillen's Resolution Theorem in algebraic K-theory provides a powerful
computational tool for calculating K-groups of exact categories. At the level of K 0, this result …
