Perfectoid signature, perfectoid Hilbert-Kunz multiplicity, and an application to local fundamental groups

H Cai, S Lee, L Ma, K Schwede, K Tucker - arXiv preprint arXiv …, 2022 - arxiv.org
We define a (perfectoid) mixed characteristic version of $ F $-signature and Hilbert-Kunz
multiplicity by utilizing the perfectoidization functor of Bhatt-Scholze and Faltings' normalized …

On birational Macaulayfications and Cohen–Macaulay canonical modules

P Schenzel - Journal of Algebra, 2004 - Elsevier
The aim of the paper is twofold. At first there is a characterization of those local domains
admitting a birational Macaulayfication. It turns out that a local domain A, quotient of a …

On sequentially Cohen-Macaulay modules

NT Cuong, DT Cuong - Kodai Mathematical Journal, 2007 - jstage.jst.go.jp
In this paper we introduce the notion of good systems of parameters with respect to certain
increasing filtration of submodules of a Noetherian module in order to prove several …

Lyubeznik table of sequentially Cohen–Macaulay rings

J Álvarez Montaner - Communications in Algebra, 2015 - Taylor & Francis
We prove that sequentially Cohen–Macaulay rings in positive characteristic, as well as
sequentially Cohen–Macaulay Stanley–Reisner rings in any characteristic, have trivial …

dd-Sequences and partial Euler–Poincaré characteristics of Koszul complex

NT Cuong, DT Cuong - Journal of Algebra and Its Applications, 2007 - World Scientific
The aim of this paper is to introduce a new notion of sequences called dd-sequences and
show that this notion may be convenient for studying the polynomial property of partial Euler …

On the structure of finitely generated modules over quotients of Cohen-Macaulay local rings

NT Cuong, PH Quy - arXiv preprint arXiv:1612.07638, 2016 - arxiv.org
Let $(R,\frak m) $ be a homomorphic image of a Cohen-Macaulay local ring and $ M $ a
finitely generated $ R $-module. We use the splitting of local cohomology to shed a new light …

Top local cohomology and the catenaricity of the unmixed support of a finitely generated module

NT Cuong#, NT Dung, LT Nhan* - Communications in Algebra, 2007 - Taylor & Francis
Let (R, 𝔪) be a Noetherian local ring and M a finitely generated R-module with dim M= d.
This paper is concerned with the following property for the top local cohomology module: In …
