A numerical method for the computation of faber polynomials for starlike domains [PDF]

open access: yes, 1991
We describe a simple numerical process (based on the Theodorsen method for conformal mapping ) for computing approximations to Faber polynomials for starlike ...

Structured matrix methods for computations on Bernstein basis polynomials [PDF]

open access: yes, 2013
This thesis considers structure preserving matrix methods for computations on Bernstein polynomials whose coefficients are corrupted by noise. The ill-posed operations of greatest common divisor computations and polynomial division are considered, and it

On orthogonal polynomials and related discrete integrable systems [PDF]

open access: yes, 2006
Orthogonal polynomials arise in many areas of mathematics and have been the subject of interest by many mathematicians. In recent years this interest has often arisen from outside the orthogonal polynomial community after their connection with ...

Best multi Approximation of Unbounded Functions by Using Modulus of Smoothness [PDF]

open access: yesمجلة جامعة الانبار للعلوم الصرفة, 2021
We present an estimate of the degree of best multi approximation of unbounded function on 〖[-1,1]〗^d by algebraic polynomials in weighted space. The studied of the relation between the best approximation of derivatives functions in weighted space and the

Trigonometric Approximation by Modulus of Smoothness in Lp,α (X)

open access: yesAl-Mustansiriyah Journal of Science, 2021
In this paper, we study the approximate properties of functions by means of trigonometric polynomials in weighted spaces. Relationships between modulus of smoothness of function derivatives and those of the jobs themselves are introduced. In the weighted

Uniform Convergence of Some Extremal Polynomials in Domain with Corners on the Boundary

open access: yesJournal of Inequalities and Applications, 2010
The aim of this paper is to investigate approximation properties of some extremal polynomials in Ap1, p>0 space. We are interested in finding approximation rate of extremal polynomials to Riemann function in Ap1 and C-norms on domains bounded by ...
