[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 …

Silting objects
L Angeleri Hügel - Bulletin of the London Mathematical Society, 2019 - Wiley Online Library
We give an overview of recent developments in silting theory. After an introduction on torsion
pairs in triangulated categories, we discuss and compare different notions of silting and …

Torsion pairs in silting theory
L Angeleri Hügel, F Marks, J Vitória - Pacific Journal of Mathematics, 2017 - msp.org
In the setting of compactly generated triangulated categories, we show that the heart of a
(co) silting t-structure is a Grothendieck category if and only if the (co) silting object satisfies …

Tilting, cotilting, and spectra of commutative Noetherian rings
L Angeleri Hügel, D Pospíšil, J Šťovíček… - Transactions of the …, 2014 - ams.org
We classify all tilting and cotilting classes over commutative noetherian rings in terms of
descending sequences of specialization closed subsets of the Zariski spectrum …

Mutation and torsion pairs
LA Hügel, R Laking, J Šťovíček, J Vitória - arXiv preprint arXiv:2201.02147, 2022 - arxiv.org
Mutation of compact silting objects is a fundamental operation in the representation theory of
finite-dimensional algebras due to its connections to cluster theory and to the lattice of …

Cosilting modules
S Breaz, F Pop - Algebras and Representation Theory, 2017 - Springer
We study the class of modules, called cosilting modules, which are defined as the
categorical duals of silting modules. Several characterizations of these modules and …

[HTML][HTML] Cosilting complexes and AIR-cotilting modules
P Zhang, J Wei - Journal of Algebra, 2017 - Elsevier
We introduce and study the new concepts of cosilting complexes, cosilting modules and AIR-
cotilting modules. We prove that the three concepts AIR-cotilting modules, cosilting modules …

[HTML][HTML] Silting and cosilting classes in derived categories
F Marks, J Vitória - Journal of Algebra, 2018 - Elsevier
An important result in tilting theory states that a class of modules over a ring is a tilting class
if and only if it is the Ext-orthogonal class to a set of compact modules of bounded projective …
