[图书][B] Purity, spectra and localisation
M Prest - 2009 - books.google.com
It is possible to associate a topological space to the category of modules over any ring. This
space, the Ziegler spectrum, is based on the indecomposable pure-injective modules …

Torsion classes, wide subcategories and localisations
F Marks, J Šťovíček - Bulletin of the London Mathematical …, 2017 - Wiley Online Library
For a finite‐dimensional algebra A, we establish correspondences between torsion classes
and wide subcategories in mod (A). In case A is representation finite, we obtain an explicit …

Wide subcategories and lattices of torsion classes
S Asai, C Pfeifer - Algebras and Representation Theory, 2022 - Springer
In this paper, we study the relationship between wide subcategories and torsion classes of
an abelian length category AA from the point of view of lattice theory. Motivated by τ-tilting …

Dominant local rings and subcategory classification
R Takahashi - International Mathematics Research Notices, 2023 - academic.oup.com
We introduce a new notion of commutative noetherian local rings, which we call dominant.
We explore fundamental properties of dominant local rings and compare them with other …

Wide subcategories are semistable
T Yurikusa - arXiv preprint arXiv:1705.07636, 2017 - arxiv.org
For an arbitrary finite dimensional algebra $\Lambda $, we prove that any wide subcategory
of $\mathsf {mod}\Lambda $ satisfying a certain finiteness condition is $\theta $-semistable …

Cofiniteness of local cohomology modules and subcategories of modules
R Takahashi, N Wakasugi - Collectanea Mathematica, 2023 - Springer
Let R be a commutative noetherian ring and I an ideal of R. Assume that for all integers i the
local cohomology module HI i (R) is I-cofinite. Suppose that R p is a regular local ring for all …
