Weighted approximation by q-Ibragimov-Gadjiev operators [PDF]
The present paper deals with a q-generalization of Ibragimov-Gadjiev operators which were constructed by Ibragimov and Gadjiev in 1970. We studied convergence properties on the interval [0;infinity) and obtain rate of convergence in terms of weighted ...

A new construction of Lupaş operators and its approximation properties
The aim of this paper is to study a new generalization of Lupaş-type operators whose construction depends on a real-valued function ρ by using two sequences u m $u_{m} $ and v m $v_{m}$ of functions.

On the Approximation by Balázs–Szabados Operators
We present three new approximation properties of the Balázs–Szabados operators. Firstly, we prove that, in certain cases, these operators approximate some super-exponential functions on compact intervals.

Approximation by sampling Kantorovich series in weighted spaces of functions [PDF]
This paper studies the convergence of the so-called sampling Kantorovich operators for functions belonging to weighted spaces of continuous functions. This setting allows us to establish uniform convergence results for functions that are not necessarily ...

Mixed modulus of continuity in the Lebesgue spaces with Muckenhouptweights and their properties
Summary: Main properties of the mixed modulus of continuity in the Lebesgue spaces with Muckenhoupt weights are investigated. We use the mixed modulus of continuity to obtain Potapov type direct and inverse estimates of angular trigonometric approximation of functions in these spaces. We prove an equivalence between the mixed modulus of continuity and \

Rate of Weighted Statistical Convergence for Generalized Blending-Type Bernstein-Kantorovich Operators [PDF]
An alternative approach, known today as the Bernstein polynomials, to the Weierstrass uniform approximation theorem was provided by Bernstein. These basis polynomials have attained increasing momentum, especially in operator theory, integral equations ...

In this paper, we establish a link between the Szász-Durrmeyer type operators and multiple Appell polynomials. We study a quantitative-Voronovskaya type theorem in terms of weighted modulus of smoothness using sixth order central moment and Grüss ...

Approximation of functions of two variables by certain linear positive operators [PDF]
Bascanbaz-Tunca, Gulen/0000-0003-3216-1661;We introduce certain linear positive operators and study some approximation properties of these operators in the space of functions, continuous on a compact set, of two variables.
