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 …

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 …

On the abundance of silting modules

LA Hügel - Surveys in Representation Theory of Algebras” …, 2018 - books.google.com
Silting modules are abundant. Indeed, they parametrise the definable torsion classes over a
noetherian ring, and the hereditary torsion pairs of finite type over a commutative ring. Also …

[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 …

[HTML][HTML] Silting theory in triangulated categories with coproducts

P Nicolás, M Saorín, A Zvonareva - Journal of Pure and Applied Algebra, 2019 - Elsevier
We introduce the notion of noncompact (partial) silting and (partial) tilting sets and objects in
any triangulated category D with arbitrary (set-indexed) coproducts. We show that …

Silting modules

LA Hügel, F Marks, J Vitória - … Mathematics Research Notices, 2016 - academic.oup.com
We introduce the new concept of silting modules. These modules generalize tilting modules
over an arbitrary ring, as well as support-tilting modules over a finite dimensional algebra …

[HTML][HTML] Silting modules and ring epimorphisms

LA Hügel, F Marks, J Vitória - Advances in Mathematics, 2016 - Elsevier
There are well-known constructions relating ring epimorphisms and tilting modules. The new
notion of silting module provides a wider framework for studying this interplay. To every …

Silting, cosilting, and extensions of commutative ring

S Breaz, M Hrbek, GC Modoi - arXiv preprint arXiv:2204.01374, 2022 - arxiv.org
We study the transfer of (co) silting objects in derived categories of module categories via
the extension functors induced by a morphism of commutative rings. It is proved that the …
