Arithmetic geometry of toric varieties. Metrics, measures and heights

JIB Gil, P Philippon, M Sombra - arXiv preprint arXiv:1105.5584, 2011 - arxiv.org
We show that the height of a toric variety with respect to a toric metrized line bundle can be
expressed as the integral over a polytope of a certain adelic family of concave functions. To …

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 …

[HTML][HTML] Subresultants, Sylvester sums and the rational interpolation problem

C D'Andrea, T Krick, A Szanto - Journal of Symbolic Computation, 2015 - Elsevier
We present a solution for the classical univariate rational interpolation problem by means of

A Generalization of Habicht's Theorem for Subresultants of Several Univariate Polynomials

H Hong, J Meng, J Yang - arXiv preprint arXiv:2409.12727, 2024 - arxiv.org
Subresultants of two univariate polynomials are one of the most classic and ubiquitous
objects in computational algebra and algebraic geometry. In 1948, Habicht discovered and …

Closed formula for univariate subresultants in multiple roots

Number of common roots and resultant of two tropical univariate polynomials

H Hong, JR Sendra - Journal of Algebra, 2018 - Elsevier
It is well known that for two univariate polynomials over the complex number field the
number of their common roots is equal to the order of their resultant. In this paper, we show …
