On the Convergence of a Family of Chlodowsky Type Bernstein-Stancu-Schurer Operators

Journal of Function Spaces, 2018
We construct a new family of univariate Chlodowsky type Bernstein-Stancu-Schurer operators and bivariate tensor product form. We obtain the estimates of moments and central moments of these operators, obtain weighted approximation theorem, establish ...

Voronovskaja type theorem for the Lupas, q-analogue of the Bernstein operators

, 2012
In this paper, we estimate the third and the fourth order central moments for the difference of the Lupas, q-analogue of the Bernstein operator and the limit q-Lupas, operator. We also prove a quantitative variant of Voronovskaja's theorem for R-n,R-

Voronovskaja type theorem for the lupaş q-analogue of the bernstein operators

, 2012
In this paper, we estimate the third and the fourth order central moments for the difference of the Lupa ?s q-analogue of the Bernstein operator and the limit q-Lupaş operator. We also prove a quantitative variant of Voronovskaja's theorem for R <

The generalization of some results for Schurer and Schurer-Stancu operators

Journal of Numerical Analysis and Approximation Theory, 2011
In the present paper we generalize some results for Schurer and Schurer-Stancu operators. Firstly, we establish a general formula concerning calculation of test functions by Schurer operators.

On certain q-Baskakov-Durrmeyer operators

Le Matematiche, 2011
In this paper we introduce a q−analogue of Baskakaov-beta operators. We establish Voronovskaja-type theorem and obtain local error estimates by these q−operators in uniform norm by using the Ditzian-Totik weighted modulus of smoothness for 0 < q < ...

Approximation using Jakimovski–Leviatan operators of Durrmeyer type with 2D-Appell polynomials

Journal of Inequalities and Applications
This article delves into Jakimovski–Leviatan–Durrmeyer type operators based on 2D-Appell polynomials. The investigation initiates by exploring the Korovkin-type approximation theorem and its convergence rates, employing both the traditional modulus of ...

Refutation of Richard Gill's Argument Against my Disproof of Bell's Theorem [PDF]

, 2012
I identify a number of errors in Richard Gill's purported refutation of my disproof of Bell's theorem. In particular, I point out that his central argument is based, not only on a rather trivial misreading of my counterexample to Bell's theorem, but also

Approximation by quaternion (p,q) $(p,q)$-Bernstein polynomials and Voronovskaja type result on compact disk

, 2018
In this paper, we define the (p,q) $(p,q)$-Bernstein polynomials of degree m of a quaternion variable. We obtain some approximation results, and also the Voronovskaja type result with quantitative upper estimates is ...
