On the Coefficients of Hilbert Quasipolynomials
Winfried Bruns, Bogdan Ichim
The Hilbert function of a module over a positively graded algebra is of quasi-polynomial type (Hilbert--Serre). We derive an upper bound for its grade, i.e. the index from which on…

Length Formulas for the Homology of Generalized Koszul Complexes
Bogdan Ichim, Udo Vetter
Let be a finite module over a noetherian ring with a free resolution of length 1. We consider the generalized Koszul complexes associated with a ma…

Koszul Bicomplexes and Generalized Koszul Complexes in Projective Dimension One
Bogdan Ichim, Udo Vetter
We describe Koszul type complexes associated with a linear map from any module to a free module, and vice versa with a linear map from a free module to an arbitrary module, general…
