Korovkin-type Theorems and Approximation by Positive Linear Operators [PDF]

, 2010
This survey paper contains a detailed self-contained introduction to Korovkin-type theorems and to some of their applications concerning the approximation of continuous functions as well as of L^p-functions, by means of positive linear operators.

Limit theorems for iterates of the Sz\'asz-Mirakyan operator in probabilistic view

, 2022
The Sz\'asz-Mirakyan operator is known as a positive linear operator which uniformly approximates a certain class of continuous functions on the half line.

Convergence by Class of Kantorovich-Type q-Szász Operators and Comprehensive Results

Mathematics
In this paper, we primarily use Stancu variants of Kantorovich-type operators to investigate the convergence and other associated properties of new Szász–Mirakjan operators.

A generalization of the Lupaș \(q\)-analogue of the Bernstein operator

Journal of Numerical Analysis and Approximation Theory, 2016
We introduce a Stancu type generalization of the Lupaș \(q\)-analogue of the Bernstein operator via the parameter \(\alpha\). The construction of our operator is based on the generalization of Gauss identity involving \(q\)-integers.

Shape preserving approximation properties to family of α-Bernstein shifted knot operators

Journal of Inequalities and Applications
The main idea of this paper is to obtain approximation results by utilizing the shifted knots properties of the family of α-Bernstein operators. We examine some basic results and estimate the moments of this new family of α-Bernstein operators. We derive
