On The (De)Homogenization of Sagbi-Gröbner Bases for Modules

open access: yesAnalele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica
This article explores the behavior of Sagbi-Gröbner bases for modules over polynomial subalgebras under the process of homogenization and dehomogenization.

On the Hilbert depth of the quotient ring of the edge ideal of a star graph

open access: yesAnalele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica
Let Sn = K[x1, . . . , xn, y] and In = (x1y, x2y, . . . , xny) ⊂ Sn be the edge ideal of star graph. We prove that hdepth (Sn/In)≥⌈n2⌉+⌊n⌋-2\left( {S_n /I_n } \right) \ge \left\lceil {{n \over 2}} \right\rceil + \left\lfloor {\sqrt n } \right\rfloor -

On the Hilbert depth of the Hilbert function of a finitely generated graded module

open access: yesAnalele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica
Let K be a field, A a standard graded K-algebra and M a finitely generated graded A-module. Inspired by our previous works, see [2] and [3], we study the invariant called Hilbert depth of hM, that is hdepth(hM)=max{d:∑j≤k(-1)k-j(d-jk-j)hM(j)≥0  for  all ...

Dependency Relations Among the Shifts of a Multivariate Refinable Distribution

open access: yes, 1998
. Refinable functions are an intrinsic part of subdivision schemes and wavelet constructions. The relevant properties of such functions must usually be determined from their refinement masks.
