Some characterizations of local rings via reducing dimensions

O Celikbas, S Dey, T Kobayashi, H Matsui - arXiv preprint arXiv …, 2022 - arxiv.org
In this paper we study homological dimensions of finitely generated modules over
commutative Noetherian local rings, called reducing homological dimensions. We obtain …

On the reducing projective dimension of the residue field

O Celikbas, S Dey, T Kobayashi, H Matsui - arXiv preprint arXiv …, 2022 - arxiv.org
In this paper we are concerned with certain invariants of modules, called reducing
invariants, which have been recently introduced and studied by Araya-Celikbas and Araya …

If M is a nonzero finitely generated module over a commutative Noetherian local ring R such
that M has finite injective dimension and finite Gorenstein dimension, then it follows from a …

Depth formula for modules of finite reducing projective dimension

O Celikbas, T Kobayashi, B Laverty… - arXiv preprint arXiv …, 2023 - arxiv.org
We prove that the depth formula holds for two finitely generated Tor-independent modules
