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

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