Schur-Type Inequalities for Complex Polynomials with no Zeros in the Unit Disk

open access: yesJournal of Inequalities and Applications, 2007
Starting out from a question posed by T. Erdélyi and J. Szabados, we consider Schur-type inequalities for the classes of complex algebraic polynomials having no zeros within the unit disk D.

Linear Optimization of Polynomial Rational Functions: Applications for Positivity Analysis

open access: yesMathematics, 2020
In this paper, we provide tight linear lower bounding functions for multivariate polynomials given over boxes. These functions are obtained by the expansion of polynomials into Bernstein basis and using the linear least squares function.

Solving Nonlinear Multi-Order Fractional Differential Equations Using Bernstein Polynomials

open access: yesIEEE Access, 2023
This paper introduces two novel methods for solving multi-order fractional differential equations using Bernstein polynomials. The first method, referred to as the fractional operational matrix of differentiation of Bernstein polynomials, is employed to ...

Bernstein Polynomials

open access: yesMapana Journal of Sciences, 2021
Bernstein polynomials (aka, B-polys) have excellent properties allowing them to be used as basis functions in many applications of physics. In this paper, a brief tutorial description of their properties is given and then their use in obtaining B-polys, B-splines or Basis spline functions, Bezier curves and ODE solution curves, is computationally ...

Approximation properties of bivariate complex $q$-Bernstein polynomials in the case $q>1$ [PDF]

open access: yes, 2012
summary:In the paper, we discuss convergence properties and Voronovskaja type theorem for bivariate $q$-Bernstein polynomials for a function analytic in the polydisc $D_{R_{1}}\times D_{R_{2}}=\{z\in C\colon \vert z\vert 1$.

A Generalization of the Bernstein Polynomials

open access: yesJournal of Mathematical Analysis and Applications, 1997
The author generalizes the Bernstein polynomials by taking averages of point evaluations of the function \(f\) instead of the usual values \(f(i/n)\). The number of point evaluations \(s_n\) taken for the \(n\)th polynomial, may grow to \(\infty\) as \(n\to\infty\), but it is necessary and sufficient for insuring approximation of continuous functions ...
