Smooth and algebraic invariants of a group action: local and global constructions

E Hubert, IA Kogan - Foundations of Computational Mathematics, 2007 - Springer
We provide an algebraic formulation of the moving frame method for constructing local
smooth invariants on a manifold under an action of a Lie group. This formulation gives rise to …

New and old results in resultant theory

AY Morozov, SR Shakirov - Theoretical and Mathematical Physics, 2010 - Springer
Resultants play an increasingly important role in modern theoretical physics: they appear
whenever we have nonlinear (polynomial) equations, nonquadratic forms, or non-Gaussian …

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 …

[HTML][HTML] Scalar q-subresultants and Dickson matrices

B Csajbók - Journal of Algebra, 2020 - Elsevier
Following the ideas of Ore and Li we study q-analogues of scalar subresultants and show
how these results can be applied to determine the rank of an F q-linear transformation f of F …

Subresultants of several univariate polynomials in Newton basis

W Wang, J Yang - Journal of Symbolic Computation, 2025 - Elsevier
In this paper, we consider the problem of formulating the subresultant polynomials for
several univariate polynomials in Newton basis. It is required that the resulting subresultant …

Computing greatest common divisor of several parametric univariate polynomials via generalized subresultant polynomials

H Hong, J Yang - arXiv preprint arXiv:2401.00408, 2023 - arxiv.org
In this paper, we tackle the following problem: compute the gcd for several univariate
polynomials with parametric coefficients. It amounts to partitioning the parameter space …
