Local and global results for modified Sz\'{a}sz - Mirakjan operators

open access: yes, 2016
In this paper, we study a natural modification of Sz\'{a}sz - Mirakjan operators. It is shown by discussing many important established results for Sz\'{a}sz - Mirakjan operators.

Korovkin Second Theorem via -Statistical -Summability

open access: yesAbstract and Applied Analysis, 2013
Korovkin type approximation theorems are useful tools to check whether a given sequence of positive linear operators on of all continuous functions on the real interval is an approximation process.

Korovkin-Type Theorems for Modular Ψ-A-Statistical Convergence

open access: yesJournal of Function Spaces, 2015
We deal with a new type of statistical convergence for double sequences, called Ψ-A-statistical convergence, and we prove a Korovkin-type approximation theorem with respect to this type of convergence in modular spaces.

Some Applications of New Modified q-Integral Type Operators

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2015
We introduce a new sequence of q-integral operators. We show that it is a weighted approximation process in the polynomial space of continuous functions defined on unit interval.

Korovkin type approximation theorems on the disk algebra

open access: yesHokkaido Mathematical Journal, 2000
Let \(A(\Gamma)\) denote the space of complex valued functions defined on the unit circle \(\Gamma\) in \(\mathbb{C}\) which can be extended analytically in the open unit disc. A bounded linear operator \(T\) on \(A(\Gamma)\) is called a BKW-operator (in the sense of Takahasi) for the set of test functions \(S\subset A(\Gamma)\) if \((T_n)_{n\in N ...

Invariant mean and a Korovkin-type approximation theorem [PDF]

open access: yesJournal of Inequalities and Applications, 2013
In this paper we apply this form of convergence to prove some Korovkin-type approximation theorem by using the test functions 1, e –x , e –2x , which generalizes the results of Boyanov and Veselinov (Bull. Math. Soc. Sci. Math. Roum. 14(62):9-13, 1970).

Weighted Korovkin-Type Theorem and Some Properties of Szász–Mirakjan Operators Preserving Exponential Functions via Power Series Statistical Convergence

open access: yesJournal of Function Spaces
In this article, we establish a weighted Korovkin-type approximation theorem within the framework of power series statistical convergence and provide a systematic extension of classical Korovkin theory to weighted function spaces.

Bézier Form of Quantum λ‐Bernstein–Schurer Operators With Associated Approximation Properties

open access: yesJournal of Mathematics, Volume 2026, Issue 1, 2026.
We introduce a Bézier form of Schurer‐type modification of the quantum λ‐Bernstein operators, extending the classical Schurer operators through the Bézier basis with shape parameter −1 ≤ λ ≤ 1. By applying Korovkin’s theorem, we obtain both global and local approximation results.

On generalized Baskakov-Durrmeyer-Stancu type operators

open access: yesDemonstratio Mathematica, 2017
In this paper, we study some local approximation properties of generalized Baskakov-Durrmeyer-Stancu operators. First, we establish a recurrence relation for the central moments of these operators, then we obtain a local direct result in terms of the ...
