The 𝑡-structure induced by an 𝑛-tilting module

S Bazzoni - Transactions of the American Mathematical Society, 2019 - ams.org
We study the $ t $-structure induced by an $ n $-tilting module $ T $ in the derived category
$\mathcal {D}(R) $ of a ring $ R $. Our main objective is to determine when the heart of the …

Ringel modules and homological subcategories

H Chen, C Xi - arXiv preprint arXiv:1206.0522, 2012 - arxiv.org
Given a good $ n $-tilting module $ T $ over a ring $ A $, let $ B $ be the endomorphism ring
of $ T $, it is an open question whether the kernel of the left-derived functor $ T\otimes^ L_B …

S Bazzoni, F Mantese, A Tonolo - Proceedings of the American …, 2011 - ams.org
Let $ T_R $ be a right $ n $-tilting module over an arbitrary associative ring $ R $. In this
paper we prove that there exists an $ n $-tilting module $ T'_R $ equivalent to $ T_R $ which …

Let $ T $ be a $1 $-tilting module whose tilting torsion pair $({\mathcal T},{\mathcal F}) $ has
the property that the heart ${\mathcal H} _t $ of the induced $ t $-structure (in the derived …

[HTML][HTML] Direct limits in the heart of a t-structure: the case of a torsion pair

CE Parra, M Saorín - Journal of pure and applied algebra, 2015 - Elsevier
We study the behavior of direct limits in the heart of a t-structure. We prove that, for any
compactly generated t-structure in a triangulated category with coproducts, countable direct …

[PDF][PDF] Derived equivalence induced by n-tilting modules

S Bazzoni, F Mantese, A Tonolo - arXiv preprint arXiv:0905.3696, 2009 - researchgate.net
Let TR be a right n-tilting module over an arbitrary associative ring R. In this paper we prove
that there exists a n-tilting module T′ R equivalent to TR which induces a derived …

Hearts of t-structures in the derived category of a commutative Noetherian ring

C Parra, M Saorin - Transactions of the American Mathematical Society, 2017 - ams.org
Let $ R $ be a commutative Noetherian ring and let $\mathcal D (R) $ be its (unbounded)
derived category. We show that all compactly generated t-structures in $\mathcal D (R) …

[HTML][HTML] Simples in a cotilting heart

L Angeleri Hügel, I Herzog, R Laking - Mathematische Zeitschrift, 2024 - Springer
Every cotilting module over a ring R induces a t-structure with a Grothendieck heart in the
derived category D (Mod-R). We determine the simple objects in this heart and their injective …

On the vanishing of Ext over formal triangular matrix rings

J Asadollahi, S Salarian - 2006 - degruyter.com
Let A and B be two rings, M be a left B, right A bimodule and be the formal triangular matrix
ring. It is known that the category of right T-modules is equivalent to the category Ω of triples …

Good tilting modules and recollements of derived module categories

H Chen, C Xi - Proceedings of the London Mathematical Society, 2012 - academic.oup.com
Let T be an infinitely generated tilting module of projective dimension at most one over an
arbitrary associative ring A, and let B be the endomorphism ring of T. We prove that if T is …
