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

Mathematics, 2022 An alternative approach, known today as the Bernstein polynomials, to the Weierstrass uniform approximation theorem was provided by Bernstein. These basis polynomials have attained increasing momentum, especially in operator theory, integral equations ...

Uniform approximation by (quantum) polynomials [PDF]
Quantum Information and Computation, 2011 We show that quantum algorithms can be used to re-prove a classical theorem in approximation theory, Jackson's Theorem, which gives a nearly-optimal quantitative version of Weierstrass's Theorem on uniform approximation of continuous functions by polynomials. We provide two proofs, based respectively on quantum counting and on quantum phase estimation.

Approximation By Three-Dimensional q-Bernstein-Chlodowsky Polynomials
Sakarya Üniversitesi Fen Bilimleri Enstitüsü Dergisi, 2018 In the present paper we introduce positive linear three-dimensionalBernstein-Chlodowsky polynomials on a non-tetrahedron domain and we get theirq-analogue.

Trigonometric Approximation by Modulus of Smoothness in Lp,α (X)
Al-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
Journal 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 ...

Monotone Approximation by Algebraic Polynomials [PDF]
Transactions of the American Mathematical Society, 1970 A given real continuous function f on [a, b] is approximated by polynomials P n {P_n} of degree n that are subject to certain restrictions. Let 1 ≦ k 1 > ⋯ > k p

Approximation by double Walsh polynomials
International Journal of Mathematics and Mathematical Sciences, 1992 We study the rate of approximation by rectangular partial sums, Cesàro means, and de la Vallée Poussin means of double Walsh-Fourier series of a function in a homogeneous Banach space X.
