Estimates in direct inequalities for the Szász–Mirakyan operator [PDF]

open access: yes, 2022
This paper deals with the approximation of continuous functions by the classical Szász–Mirakyan operator. We give new bounds for the constant in front of the second order Ditzian–Totik modulus of smoothness in direct inequalities.

Voronovskaya-Type Theorems for Derivatives of the Bernstein-Chlodovsky Polynomials and the Szász-Mirakyan Operator [PDF]

open access: yes, 2009
This paper is devoted to a study of a Voronovskaya-type theorem for the derivative of the Bernstein–Chlodovsky polynomials and to a comparison of its approximation effectiveness with the corresponding theorem for the much better-known Szász–Mirakyan ...

Boundedness of a Kantorovich type of the Szász-Mirakjan Operator [PDF]

open access: yesITM Web of Conferences
Let Bn f represent the n-th Bernstein polynomial for f for each n ϵ ℕ and f ϵ C ([0, 1]) . Then for any f ϵ C ([0, 1]), the sequence {Bn f} converges uniformly to f.

On the Rate of Convergence of the Generalized Szász Type Operators for Functions of Bounded Variation [PDF]

open access: yes, 1998
In this article we introduce the Szász–Bézier operatorSn,αwhich is the modified form of the Szász–Mirakyan operator. By means of construction of suitable functions and the methods of Bojanic–Vuillemier [J. Approx.

Best constants in preservation of global smoothness for Szász–Mirakyan operators [PDF]

open access: yes, 2008
We obtain the best possible constants in preservation inequalities concerning the usual first modulus of continuity for the classical Szász–Mirakyan operator.

A remark on a modified Szász-Mirakjan operator [PDF]

open access: yes, 1999
We prove that, for a sequence of positive numbers δ(n), if $n^{1/2}δ(n)\not\to\infty$ as $n\to\infty$, to guarantee that the modified Szász-Mirakjan operators $S_{n,δ}(f,x)$ converge to f(x) at every point, f must be identically ...

Generalization of Szász–Mirakjan–Kantorovich operators using multiple Appell polynomials

open access: yesJournal of Inequalities and Applications, 2020
The purpose of the present paper is to introduce and study a sequence of positive linear operators defined on suitable spaces of measurable functions on [ 0 , ∞ ) $[0,\infty )$ and continuous function spaces with polynomial weights.
