Quantitative estimates of convergence in nonlinear operator extensions of Korovkin's theorems

open access: yes, 2023
This paper is aimed to prove a quantitative estimate (in terms of the modulus of continuity) for the convergence in the nonlinear version of Korovkin's theorem for sequences of weakly nonlinear and monotone operators defined on spaces of continuous real ...

On -analogue of two parametric Stancu-Beta operators [PDF]

open access: yes, 2007
Our purpose is to introduce a two-parametric ( p , q ) $(p, q)$ -analogue of the Stancu-Beta operators. We study approximating properties of these operators using the Korovkin approximation theorem and also study a direct theorem.

Approximation by q-analogue of modified Jakimovski-Leviatan-Stancu type operators

open access: yesDemonstratio Mathematica, 2017
In this paper, we introduce the q-analogue of the Jakimovski-Leviatan type modified operators introduced by Atakut with the help of the q-Appell polynomials.We obtain some approximation results via the well-known Korovkin’s theorem for these operators.We

Korovkin-Type Results on Convergence of Sequences of Positive Linear Maps on Function Spaces [PDF]

open access: yes, 2019
In this paper, we deal with the convergence of sequences of positive linear maps to a (not assumed to be linear) isometry on spaces of continuous functions.

Operator version of Korovkin Theorem; Degree of Convergence and its Applications

open access: yes, 2022
In a recent article, Dumitru Popa proved an operator version of the Korovkin theorem. We recall the quantitative version of the Korovkin theorem obtained by O. Shisha and B. Mond in 1968.

A Kantorovich Type of Szasz Operators Including Brenke-Type Polynomials

open access: yesAbstract and Applied Analysis, 2012
We give a Kantorovich variant of a generalization of Szasz operators defined by means of the Brenke-type polynomials and obtain convergence properties of these operators by using Korovkin's theorem.
