Finiteness of local homology modules

Shahram Rezaei (2020)

Archivum Mathematicum

Let I be an ideal of Noetherian ring R and M a finitely generated R -module. In this paper, we introduce the concept of weakly colaskerian modules and by using this concept, we give some vanishing and finiteness results for local homology modules. Let I M : = Ann R ( M / I M ) , we will prove that for any integer n If ...

Formes d'inertie et complexe de Koszul associés à des polynômes plurihomogènes.

Azzouz Awane, Abdelouahab Chkiriba, Michel Goze (2005)

Revista Matemática Complutense

The existence of common zero of a family of polynomials has led to the study of inertial forms, whose homogeneous part of degree 0 constitutes the ideal resultant. The Kozsul and Cech cohomologies groups play a fundamental role in this study. An analogueous of Hurwitz theorem is given, and also, one finds a N. H. McCoy theorem in a particular case of this study.
