[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 …

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 …

On locally coherent hearts

M Saorín - Pacific Journal of Mathematics, 2017 - msp.org
Let G be a locally coherent Grothendieck category. We show that, under particular
conditions, if a t-structure τ in the unbounded derived category D (G) restricts to the bounded …

[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 …

Pure projective tilting modules

S Bazzoni, I Herzog, P Příhoda, J Šaroch… - arXiv preprint arXiv …, 2017 - arxiv.org
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] Addendum to “Direct limits in the heart of a t-structure: The case of a torsion pair”[J. Pure Appl. Algebra 219 (9)(2015) 4117–4143]

CE Parra, M Saorín - Journal of Pure and Applied Algebra, 2016 - Elsevier
Let G be a Grothendieck category, let t=(T, F) be a torsion pair in G and let (U t, W t) be the
associated Happel–Reiten–Smalø t-structure in the derived category D (G). We prove that …

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) …

CG torsion pairs

D Bravo, CE Parra - Journal of Algebra and Its Applications, 2019 - World Scientific
We investigate conditions when the t-structure of Happel–Reiten–Smalø associated to a
torsion pair is a compactly generated t-structure. The concept of at CG torsion pair is …

On the heart associated with a torsion pair

F Mantese, A Tonolo - Topology and its Applications, 2012 - Elsevier
Given an associative ring R and a torsion pair (T, F) in the category of right R-modules, the
heartH (T, F) associated with (T, F) is an abelian subcategory of the bounded derived …
