Complex Generalized Stancu-Schurer Operators

Mathematica Slovaca
Abstract In the present study, we determine a Schurer type of complex generalized Stancu operators and examine its some approximation properties. Firstly, we obtain upper quantitative estimates for the convergence and then we get lower estimates from a qualitative Voronovskaja-type result for these specified operators attached to the ...

A generalization of Stancu-Mühlbach operators

Constructive Approximation, 1991
Let X be a metrizable convex compact subset embedded in a local convex Hausdorff space and \((a_ n)_{n\in {\mathbb{N}}}\) a sequence of nonnegative real numbers converging to zero. The well-known sequence \((Q_ n,a_ n)_{n\in {\mathbb{N}}}\) of Stancu-Mühlbach operators on C[0,1] (reducing for \(a_ n=0\) and \(a_ n=-1/n\) respectively to Bernstein and ...

Stancu type generalization of the q-Phillips operators

Numerical Algorithms, 2015
In the current article, the authors introduced the Stancu type \(q\)-Phillips operators and study some of their approximation properties. First, they estimated the moments of these operators then investigated their local and weighted approximation properties and statistical convergence.

Exponential Kantorovich-Stancu operators

Bulletin of the Transilvania University of Brasov. Series III: Mathematics and Computer Science
In this paper we will obtain some Bernstein-Kantorovich operators modified in Stancu sense which preserve exponential function eμx, where μ > 0. Concerning these operators we prove they verify Korovkin’s theorem conditions and also that they approximate functions from a weighted Lp space.

Approximation by Stancu–Chlodowsky type λ-Bernstein operators

Journal of Applied Analysis, 2020
Abstract In this paper, we give some approximation properties by Stancu–Chlodowsky type λ-Bernstein operators in the polynomial weighted space and obtain the convergence properties of these operators by using Korovkin’s theorem. We also establish the direct result and the Voronovskaja type asymptotic formula.

Over-iterates of Bernstein-Stancu operators

Calcolo, 2007
In this paper the authors obtain convergence results for over-iterates of generalized Bernstein--Stancu operators. They use the spectrum of the operators involved. Therefore it is possible to make global statements on \([0,1]\). This is different from a previous result by \textit{I. A. Rus} [Studia Univ. Babes-Bolyai. Math. 47(4), 101--104 (2002)].
