Realisation functors in tilting theory

C Psaroudakis, J Vitória - Mathematische Zeitschrift, 2018 - Springer
Derived equivalences and t-structures are closely related. We use realisation functors
associated to t-structures in triangulated categories to establish a derived Morita theory for …

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 …

Silting modules over commutative rings

LA Hügel, M Hrbek - International Mathematics Research …, 2017 - academic.oup.com
Tilting modules over commutative rings were recently classified in: they correspond
bijectively to faithful Gabriel topologies of finite type. In this note we extend this classification …

[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 …

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 …

Purity in compactly generated derivators and t-structures with Grothendieck hearts

R Laking - Mathematische Zeitschrift, 2020 - Springer
We study t-structures with Grothendieck hearts on compactly generated triangulated
categories TT that are underlying categories of strong and stable derivators. This setting …

[HTML][HTML] Dimensional homotopy t-structures in motivic homotopy theory

M Bondarko, F Déglise - Advances in Mathematics, 2017 - Elsevier
The aim of this work is to construct certain homotopy t-structures on various categories of
motivic homotopy theory, extending works of Voevodsky, Morel, Déglise and Ayoub. We …

t-Structures with Grothendieck hearts via functor categories

M Saorín, J Št'ovíček - Selecta Mathematica, 2023 - Springer
We study when the heart of at-structure in a triangulated category D with coproducts is AB5
or a Grothendieck category. If D satisfies Brown representability, at-structure has an AB5 …

Cotilting sheaves on Noetherian schemes

P Čoupek, J Šťovíček - Mathematische Zeitschrift, 2020 - Springer
We develop theory of (possibly large) cotilting objects of injective dimension at most one in
general Grothendieck categories. We show that such cotilting objects are always pure …
