Better Approximation Properties by New Modified Baskakov Operators
This paper introduces a new idea to obtain a better order of approximation for the Baskakov operator. We conclude two new operators from orders one and two of the Baskakov type. Also, we prove some directed results concerning the rate of convergence of these operators.

Fractional Trigonometric Korovkin Theory in Statistical Sense [PDF]
2000 Mathematics Subject Classification: 41A25, 41A36.In the present paper, we improve the classical trigonometric Korovkin theory by using the concept of statistical convergence from the summability theory and also by considering the fractional ...

Statistical Deferred Nörlund Summability and Korovkin-Type Approximation Theorem
The concept of the deferred Nörlund equi-statistical convergence was introduced and studied by Srivastava et al. [Rev. Real Acad. Cienc. Exactas Fís. Nat. Ser. A Mat. (RACSAM) 112 (2018), 1487–1501].

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.

In this paper we give a sufficient condition for the pointwise Korovkin property on B(X), the space of bounded real valued functions on an arbitrary countable set \(X=\{x_ 1,...,x_ j,...\}\). Our theorem follows from its \(L_ p(X,\mu)\) analogue (and conversely); here \(1\leq p0\) for all j.

Statistical Approximation for Periodic Functions of Two Variables
We prove a Korovkin type approximation theorem for a function of two variables by using the notion of statistical summability (C,1,1). We also study the rate of statistical summability (C,1,1) of positive linear operators. Finally we construct an example

Some Korovkin-type theorems using multivariate power series technique
In this note, we introduce a multivariate power series technique to test the statistical convergence of multiple sequences. Our primary goal is to establish a new multivariate Korovkin-type theorem based on this convergence approach.

Unique Hahn-Banach extensions and Korovkin’s theorem [PDF]
This paper characterizes in terms of weak topologies those bounded linear functionals on a subspace which have unique Hahn-Banach extensions to the whole linear normed space. The relationship to the Choquet boundary is discussed, and a Korovkin type theorem is obtained.

A Korovkin Theorem for Abstract Lebesgue Spaces
Let \(E\) be an AL-space (a Kakutani abstract L-space) with a generalized weak unit \(\{e_n\}\). The theorem proved here is a little stronger then the following. Theorem: Let \(\{T_i\}\) be a sequence of norm one operators defined on \(E\). Let \(L=\{ f\in E: T_if\) converges weakly to \(f\}\), and \(N=\{f\in E: T_if\) converges in norm to \(f\}\). If,

In this study, we construct a Stancu-type generalization of bivariate Bernstein–Kantorovich operators that reproduce exponential functions. Then, we investigate some approximation results for these operators.
