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 …

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 …

[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] 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 …

Definability and approximations in triangulated categories

R Laking, J Vitória - Pacific journal of mathematics, 2020 - msp.org
We give criteria for subcategories of a compactly generated algebraic triangulated category
to be precovering or preenveloping. These criteria are formulated in terms of closure …

[HTML][HTML] On purely generated α-smashing weight structures and weight-exact localizations

MV Bondarko, VA Sosnilo - Journal of Algebra, 2019 - Elsevier
This paper is dedicated to new methods of constructing weight structures and weight-exact
localizations; our arguments generalize their bounded versions considered in previous …

On perfectly generated weight structures and adjacent t-structures

MV Bondarko - Mathematische Zeitschrift, 2022 - Springer
This paper is dedicated to the study of smashing weight structures (these are the weight
structures" coherent with coproducts"), and the application of their properties to t-structures …

[HTML][HTML] t-Structures on stable derivators and Grothendieck hearts

M Saorín, J Šťovíček, S Virili - Advances in Mathematics, 2023 - Elsevier
We prove that, given any strong and stable derivator and a t-structure in its base triangulated
category D, the t-structure canonically lifts to all the (coherent) diagram categories and each …
