Brauer-Type Inclusion Sets of Zeros for Chebyshev Polynomial [PDF]

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 Coefficients and Zeros of a Polynomial [PDF]

open access: yesJournal of Approximation Theory, 1999
In continuation of work by \textit{Q. I. Rahman} [Can. Math. Bull. 13, 541-542 (1970; Zbl 0205.37802)]\ and \textit{H. Alzer} [J. Approximation Theory 81, 421-424 (1995; Zbl 0837.30007)], the author offers two results on complex polynomials of the form \(p(z)=b_{0}+b_{1}z+b_{2}z^{2}+\cdots +b_{n}z^{n}\) with \(b_{0}=1.\) One states that the absolute ...

On invariant zeros of linear systems of PDEs [PDF]

open access: yes, 2006
In this paper we provide a behavioral framework in which to describe and extend the concept of linear dynamics introduced by Fliess, from the one dimensional (1D) to the multidimensional (nD) framework.We provide an alternative description of the ...

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.

On the relations between the zeros of a polynomial and its Mahler measure [PDF]

open access: yes, 2021
International audienceIn this work, we are dealing with some properties relating the zeros of a polynomial and its Mahler measure. We provide estimates on the number of real zeros of a polynomial, lower bounds on the distance between the zeros of a ...

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 ...

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.

Equidistribution of Zeros of Polynomials [PDF]

open access: yesThe American Mathematical Monthly, 2019
A classical result of Erdos and Turan states that if a monic polynomial has small size on the unit circle and its constant coefficient is not too small, then its zeros cluster near the unit circle and become equidistributed in angle. Using Fourier analysis we give a short and self-contained proof of this result.
