Korovkin type approximation on an infinite interval via generalized matrix summability method using ideal

, 2020
Following the notion of AI -summability method for real sequences [24] we establish a Korovkin type approximation theorem for positive linear operators on UC∗[0, ∞), the Banach space of all real valued uniform continuous functions on [0, ∞) with the ...

Matrix summability methods on the approximation of multivariate q-MKZ

, 2020
. In this paper, a q-based generalization of Meyer-König and Zeller (MKZ) operators in several variables are introduced. A Korovkin-type approximation theorem via A-statistical convergence is obtained and their various Astatistical approximation ...

On two modified Phillips operators: Dedicated to Professor Heiner Gonska on the occasion of his 70th anniversary.

, 2019
In this note we introduce two new modified Phillips operators G1 and n. We obtain direct estimates for approximation of bounded continuous functions, defined on [0, ∞) by G1 , as well as for approximation of unbounded continuous functions by G2 We ...

On the approximation of Kantorovich-type Szàsz-Charlier operators

Demonstratio Mathematica
In this study, we introduce the Kantorovich-type modified Szàsz-Charlier operators and examine their approximation properties within the framework of fractional modeling and control theory. These operators are defined using the Korovkin-type theorem, and

On the power of adaption and randomization

Forum of Mathematics, Sigma
We present bounds on the maximal gain of adaptive and randomized algorithms over nonadaptive, deterministic ones for approximating linear operators on convex sets. If the sets are additionally symmetric, then our results are optimal.

A Ninth-Order Iterative Method Free from Second Derivative for Solving Nonlinear Equations

, 2011
In this paper, we study and analyze an iterative method for solving nonlinear equations with ninth order of convergence. The new proposed method is obtained by composing an iterative method obtained in Noor et al.
