N- Monotone Approximation in Weighted Space [PDF]

open access: yesمجلة جامعة الانبار للعلوم الصرفة, 2022
The purpose of this paper is to discuss the degree of best monotone multi- approximation of unbounded functions weighted space in terms the modules of smoothness by using some algebraic linear operators. In addition, introduced ,proofs some properties of

Two sharp inequalities for operators in a Hilbert space

open access: yesResearches in Mathematics, 2022
In this paper we obtained generalisations of the L. V. Taikov’s and N. Ainulloev’s sharp inequalities, which estimate a norm of function's first-order derivative (L. V. Taikov) and a norm of function's second-order derivative (N.

Approximation of GBS Type q-Jakimovski-Leviatan-Beta Integral Operators in Bögel Space

open access: yesMathematics, 2022
In the present article, we introduce the bivariate variant of Beta integral type operators based on Appell polynomials via q-calculus. We study the local and global type approximation properties for these new operators.

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

Properties of Generalized Modulus of Smoothness and Generalized Modulus of Convexity

open access: yesJournal of Harbin University of Science and Technology, 2020
Based on the definitions of generalized modulus of smoothness, the relation between generalized modulus of smoothness and t in the Banach spaces is studied, which proves three equivalent conditions of uniform normal structure and four equivalent ...

Approximation by Bézier Variant of Baskakov-Durrmeyer-Type Hybrid Operators

open access: yesJournal of Function Spaces, 2021
We give a Bézier variant of Baskakov-Durrmeyer-type hybrid operators in the present article. First, we obtain the rate of convergence by using Ditzian-Totik modulus of smoothness and also for a class of Lipschitz function.

MODIFIED MODULUS OF SMOOTHNESS AND APPROXIMATION IN WEIGHTED LORENTZ SPACES BY BOREL AND EULER MEANS

open access: yesПроблемы анализа, 2020
Using one-sided Steklov means, we introduce a new modulus of smoothness in weighted Lorentz spaces. The direct and inverse approximation theorem for this modulus of smoothness are proved.

On Fractional Smoothness of Modulus of Functions

open access: yesAnnals of Applied Mathematics, 2021
We consider the Nemytskii operators $u\to |u|$ and $u\to u^{\pm}$ in a bounded domain $\Omega$ with $C^2$ boundary.

Generalized Modulus of Smoothness in Banach Spaces

open access: yesJournal of Harbin University of Science and Technology, 2018
In order to study the geometric constants of Banach space,a new method is extended to study new constants by means of extending the modulus of smoothness to the generalized smooth mode.
