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 …

[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 …
