Tilting complexes and codimension functions over commutative noetherian rings
M Hrbek, T Nakamura, J Šťovíček - Nagoya Mathematical Journal, 2024 - cambridge.org
In the derived category of a commutative noetherian ring, we explicitly construct a silting
object associated with each sp-filtration of the Zariski spectrum satisfying the “slice” …

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 …

Duality pairs, phantom maps, and definability in triangulated categories
I Bird, J Williamson - arXiv preprint arXiv:2202.08113, 2022 - arxiv.org
We define duality triples and duality pairs in compactly generated triangulated categories
and investigate their properties. This enables us to give an elementary way to determine …

Silting, cosilting, and extensions of commutative ring
We study the transfer of (co) silting objects in derived categories of module categories via
the extension functors induced by a morphism of commutative rings. It is proved that the …

Telescope conjecture for homotopically smashing t-structures over commutative noetherian rings
M Hrbek, T Nakamura - Journal of Pure and Applied Algebra, 2021 - Elsevier
We show that any homotopically smashing t-structure in the derived category of a
commutative noetherian ring is compactly generated. This generalizes the validity of the …

Model theory in compactly generated (tensor-) triangulated categories
M Prest, R Wagstaffe - arXiv preprint arXiv:2304.10629, 2023 - arxiv.org
We give an account of model theory in the context of compactly generated triangulated and
tensor-triangulated categories ${\cal T} $. We describe pp formulas, pp-types and free …

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