Pseudo Cohen–Macaulay and pseudo generalized Cohen–Macaulay modules

NT Cuong - Journal of Algebra, 2003 - Elsevier
In this paper we study the structure of two classes of modules called pseudo Cohen–
Macaulay and pseudo generalized Cohen–Macaulay modules. We also give a …

On the least degree of polynomials bounding above the differences between lengths and multiplicities of certain systems of parameters in local rings

NT Cuong - Nagoya Mathematical Journal, 1992 - cambridge.org
Let A be a commutative local Noetherian ring with the maximal ideal m and M a finitely
generated A-module, d= dim M. It is well-known that the difference between the length and …

Local cohomology annihilators and Macaulayfication

NT Cuong, DT Cuong - Acta Mathematica Vietnamica, 2017 - Springer
The aim of this paper is to study a deep connection between local cohomology annihilators
and Macaulayfication and arithmetic Macaulayfication over a local ring. Local cohomology …

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 …

On pseudo supports and non-Cohen–Macaulay locus of finitely generated modules

NT Cuong, NTK Nga - Journal of Algebra, 2010 - Elsevier
Let (R, m) be a Noetherian local ring and M a finitely generated R-module with dimM= d. Let
i⩾ 0 be an integer. Following M. Brodmann and RY Sharp (2002)[BS1], the i-th pseudo …

[HTML][HTML] Hilbert coefficients and partial Euler–Poincaré characteristics of Koszul complexes of d-sequences

ĐT Cường, PH Nam - Journal of Algebra, 2015 - Elsevier
We construct in a finitely generated module over a Cohen–Macaulay local ring several
subquotient modules. In terms of multiplicities of these subquotients, we give precise …
