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 …

[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] A silting theorem

AB Buan, Y Zhou - Journal of Pure and Applied Algebra, 2016 - Elsevier
We give a generalization of the classical tilting theorem of Brenner and Butler. We show that
for a 2-term silting complex P in the bounded homotopy category K b (proj A) of finitely …

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] Derived equivalences via HRS-tilting

XW Chen, Z Han, Y Zhou - Advances in Mathematics, 2019 - Elsevier
Let A be an abelian category and B be the Happel-Reiten-Smalø tilt of A with respect to a
torsion pair. We give necessary and sufficient conditions for the existence of a derived …

Endomorphism algebras of 2-term silting complexes

AB Buan, Y Zhou - Algebras and Representation Theory, 2018 - Springer
We study possible values of the global dimension of endomorphism algebras of 2-term
silting complexes. We show that for any algebra A whose global dimension gl. dim A≤ 2 …

Self-orthogonal τ-tilting modules and tilting modules

X Zhang - Journal of Pure and Applied Algebra, 2022 - Elsevier
Let Λ be an Artin algebra and T a τ-tilting Λ-module. We prove that T is a tilting module if and
only if Ext Λ i (T, Fac T)= 0 for all i≥ 1, where Fac T is the full subcategory consisting of …

The representation invariants of 2-term silting complexes

Y Hu - Communications in Algebra, 2021 - Taylor & Francis
Let A be a finite dimensional k-algebra and P a 2-term silting complex in K b (proj A). In this
article, we investigate the representation dimension of End D b (A)(P) by the silting theory …
