Bézier-Summation-Integral-Type Operators That Include Pólya–Eggenberger Distribution
We define the summation-integral-type operators involving the ideas of Pólya–Eggenberger distribution and Bézier basis functions, and study some of their basic approximation properties. In addition, by means of the Ditzian–Totik modulus of smoothness, we

On the Approximation Properties of q−Analogue Bivariate λ‐Bernstein Type Operators
In this article, we establish an extension of the bivariate generalization of the q‐Bernstein type operators involving parameter λ and extension of GBS (Generalized Boolean Sum) operators of bivariate q‐Bernstein type. For the first operators, we state the Volkov‐type theorem and we obtain a Voronovskaja type and investigate the degree of approximation

Weighted Simultaneous Approximation of the Linear Combinations of Baskakov Operators
In this paper, the approximation property of the linear combinations of Baskakov operators is investigated by using a Jacobi weight function. Moreover, both the positive and inverse theorems for the weighted simultaneous approximation of the linear combinations of Baskakov operators are proved.

On the order of approximation by modified summation-integral-type operators based on two parameters
In this article, we the study generalized family of positive linear operators based on two parameters, which are a broad family of many well-known linear positive operators, e.g., Baskakov-Durrmeyer, Baskakov-Szász, Szász-Beta, Lupaş-Beta, Lupaş-Szász ...

A Note on Two Moduli of Smoothness [PDF]
We prove that for f ∈ Lp[−1, 1], 0 < p < 1 the modulus of smoothness τk(f, Δn)p,p introduced by Ivanov and Ditzian-Totik modulus of smoothness ωkφ(f, n−1)p are ...

On equivalence of moduli of smoothness of polynomials in Lp, 0, 2005
It is well known that ωr(f,t)p⩽tωr-1(f′,t)p⩽t2ωr-2(f″,t)p⩽⋯ for functions f∈Wpr, 1⩽p⩽∞.

Some approximation properties of ( p , q ) $(p,q)$ -Bernstein operators
This paper is concerned with the ( p , q ) $(p,q)$ -analog of Bernstein operators. It is proved that, when the function is convex, the ( p , q ) $(p,q)$ -Bernstein operators are monotonic decreasing, as in the classical case.

On the sharpness of a Jackson estimate by Ditzian-Totik [PDF]
Using ideas of Grünwald, Marcinkiewicz, and Vértesi concerning the divergence of interpolation processes, a counterexample is constructed which establishes that a Jackson estimate for the best approximation by algebraic polynomials given by Ditzian and ...

Pointwise Approximation for Linear Combinations of Bernstein Operators [PDF]
For linear combinations of Bernstein operators Bn, r(f, x), we give an equivalent theorem with ω2rφλ(f, t), where ω2rφλ(f, t) is the Ditzian–Totik modulus of smoothness (1−1/r⩽λ⩽1). It is the generalization of corresponding results by Z.
