Dominant local rings and subcategory classification

R Takahashi - International Mathematics Research Notices, 2023 - academic.oup.com
We introduce a new notion of commutative noetherian local rings, which we call dominant.
We explore fundamental properties of dominant local rings and compare them with other …

Persistence of homology over commutative noetherian rings

LL Avramov, SB Iyengar, S Nasseh, K Sather-Wagstaff - Journal of Algebra, 2022 - Elsevier
We describe new classes of noetherian local rings R whose finitely generated modules M
have the property that Tor i R (M, M)= 0 for i≫ 0 implies that M has finite projective …

Intersections of resolving subcategories and intersections of thick subcategories

R Takahashi - European Journal of Mathematics, 2021 - Springer
Let R be a commutative Noetherian local ring. We consider how nontrivial resolving/thick
subcategories of abelian/triangulated categories associated to R intersect. It is understood …
