Subresultants and the shape lemma

D Cox, C D'Andrea - Mathematics of Computation, 2023 - ams.org
In nice cases, a zero-dimensional complete intersection ideal over a field has a Shape
Lemma. There are also cases where the ideal is generated by the resultant and first …

On Recurrence Relations of Multi-dimensional Sequences

H Rahkooy - arXiv preprint arXiv:2410.17208, 2024 - arxiv.org
In this paper, we present a new algorithm for computing the linear recurrence relations of
multi-dimensional sequences. Existing algorithms for computing these relations arise in …

Bivariate polynomial reduction and elimination ideal over finite fields

G Villard - Journal of Symbolic Computation, 2025 - Elsevier
Given two polynomials a and b in F q [x, y] which have no non-trivial common divisors, we
prove that a generator of the elimination ideal< a, b>∩ F q [x] can be computed in quasi …

Analyzing the dual space of the saturated ideal of a regular set and the local multiplicities of its zeros

X Li, W Niu - Mathematical Methods in the Applied Sciences, 2022 - Wiley Online Library
In this paper, a method is proposed to analyze the structure of dual space of the saturated
ideal generated by a regular set and the local multiplicities of its zeros. In detail, we …

On Computing the Elimination Ideal Using Resultants with Applications to Gr\" obner Bases

M Gallet, H Rahkooy, Z Zafeirakopoulos - arXiv preprint arXiv:1307.5330, 2013 - arxiv.org
Resultants and Gr\" obner bases are crucial tools in studying polynomial elimination theory.
We investigate relations between the variety of the resultant of two polynomials and the …
