Preserving Zeros of a Polynomial [PDF]

open access: yesCommunications in Algebra, 2009
We study non-linear surjective mappings on subsets of ${\cal M}_n(F)$, which preserve the zeros of some fixed polynomials in noncommuting variables. Keywords: Matrix algebra, Multilinear polynomials, Preservers.

Polynomials with real zeros via special polynomials [PDF]

open access: yesComptes Rendus. Mathématique, 2021
In this paper, we use particular polynomials to establish some results on the real rootedness of polynomials. The considered polynomials are Bell polynomials and Hermite polynomials.

Generalizations of some Enestrom-Kakeya type results

open access: yesBibechana, 2015
In this paper we give interesting generalizations of some well-known Enestrom-Kakeya type results on the location of zeros of a complex polynomial under less restrictive conditions on the coefficients of the polynomial. BIBECHANA 13 (2016) 1-8

Brauer-Type Inclusion Sets of Zeros for Chebyshev Polynomial

open access: yesMathematics, 2019
The generalized polynomials such as Chebyshev polynomial and Hermite polynomial are widely used in interpolations and numerical fittings and so on. Therefore, it is significant to study inclusion regions of the zeros for generalized polynomials.

On the determination of the number of positive and negative polynomial zeros and their isolation

open access: yesOpen Mathematics, 2020
A novel method with two variations is proposed with which the number of positive and negative zeros of a polynomial with real coefficients and degree n can be restricted with significantly better determinacy than that provided by the Descartes rule of ...

New polynomial-based molecular descriptors with low degeneracy. [PDF]

open access: yesPLoS ONE, 2010
In this paper, we introduce a novel graph polynomial called the 'information polynomial' of a graph. This graph polynomial can be derived by using a probability distribution of the vertex set.

SMIRNOV’S INEQUALITY FOR POLYNOMIALS HAVING ZEROS OUTSIDE THE UNIT DISC

open access: yesПроблемы анализа, 2021
In 1887, the famous chemist D. I. Mendeleev posed the following problem: to estimate |𝑓 ′(𝑥)| for a real polynomial 𝑓 (𝑥), satisfying the condition |𝑓 (𝑥)| ≤ 𝑀 on [𝑎, 𝑏]. This question arose when Mendeleev was studying aqueous solutions.

ZEROS OF LACUNARY TYPE POLYNOMIALS

open access: yesEURASIAN MATHEMATICAL JOURNAL, 2022
Summary: Using Schwarz's lemma, \textit{Q. G. Mohammad} [Am. Math. Mon. 72, 631--633 (1965; Zbl 0145.30002)] proved that all zeros of the polynomial \[f(z)=a_0+a_1z+\dots+a_{n-1}z^{n-1}+a_nz^n\] with real or complex coefficients lie in the closed disc \[|z|\leqslant\frac{M'}{|a_n|}\text{ if } |a_n|\leqslant M',\] where \[M'=\max_{|z|=1}|a_0+a_1z+\dots ...

An Algebraic Criterion of Zero Solutions of Some Dynamic Systems

open access: yesAbstract and Applied Analysis, 2012
We establish some algebraic results on the zeros of some exponential polynomials and a real coefficient polynomial. Based on the basic theorem, we develop a decomposition technique to investigate the stability of two coupled systems and their discrete ...
