Recollements of Derived Categories from Two-Term Big Tilting Complexes
H Xu - Algebras and Representation Theory, 2024 - Springer
We introduce the notion of big tilting complexes over associative rings, which is a
simultaneous generalization of good tilting modules and tilting complexes over rings. Given …

A category of wide subcategories
AB Buan, BR Marsh - International Mathematics Research …, 2021 - academic.oup.com
An algebra is said to be-tilting finite provided it has only a finite number of-rigid objects up to
isomorphism. To each such algebra, we associate a category whose objects are the wide …

[PDF][PDF] Contramodules over pro-perfect topological rings, the covering property in categorical tilting theory, and homological ring epimorphisms
S Bazzoni, L Positselski - arXiv preprint arXiv:1807.10671, 2018 - math.unipd.it
For four wide classes of topological rings R, we show that all flat left R-contramodules have
projective covers if and only if all flat left R-contramodules are projective if and only if all left …
