Statistical summability (C,1) and a Korovkin type approximation theorem
, 2012 The concept of statistical summability (C,1) has recently been introduced by Móricz [Jour. Math. Anal. Appl. 275, 277-287 (2002)]. In this paper, we use this notion of summability to prove the Korovkin type approximation theorem by using the test ...

On simultaneous approximation for some modified Bernstein‐type operators
International Journal of Mathematics and Mathematical Sciences, Volume 2004, Issue 71, Page 3951-3958, 2004., 2004 We study the simultaneous approximation for a certain variant of Bernstein‐type operators.

Approximation of conic sections by weighted Lupaş post-quantum Bézier curves
Demonstratio Mathematica, 2022 This paper deals with weighted Lupaş post-quantum Bernstein blending functions and Bézier curves constructed with the help of bases via (p,q)\left(p,q)-integers. These blending functions form normalized totally positive bases.

Lp‐inverse theorem for modified beta operators
International Journal of Mathematics and Mathematical Sciences, Volume 2003, Issue 20, Page 1295-1303, 2003., 2003 We obtain a converse theorem for the linear combinations of modified beta operators whose weight function is the Baskakov operators. To prove our inverse theorem, we use the technique of linear approximating method, namely, Steklov mean.

A note on the rate of convergence for Chebyshev-Lobatto and Radau systems
Open Mathematics, 2016 This paper is devoted to Hermite interpolation with Chebyshev-Lobatto and Chebyshev-Radau nodal points. The aim of this piece of work is to establish the rate of convergence for some types of smooth functions.

Rate of convergence on Baskakov‐Beta‐Bezier operators for bounded variation functions
International Journal of Mathematics and Mathematical Sciences, Volume 32, Issue 8, Page 471-479, 2002., 2002 We introduce a new sequence of linear positive operators Bn,α(f, x), which is the Bezier variant of the well‐known Baskakov Beta operators and estimate the rate of convergence of Bn,α(f, x) for functions of bounded variation. We also propose an open problem for the readers.

A new approach to nonlinear singular integral operators depending on three parameters
Open Mathematics, 2016 In this paper, we present some theorems on weighted approximation by two dimensional nonlinear singular integral operators in the following form: Tλ(f;x,y)=∬R2Kλ(t−x,s−y,f(t,s))dsdt,(x,y)∈R2,λ∈Λ,$${T_\lambda }(f;x,y) = \iint\limits_{{\mathbb{R}^2}}K_ ...

Pell-Lucas polynomials for numerical treatment of the nonlinear fractional-order Duffing equation
Demonstratio Mathematica, 2023 The nonlinear fractional-order cubic-quintic-heptic Duffing problem will be solved through a new numerical approximation technique. The suggested method is based on the Pell-Lucas polynomials’ operational matrix in the fractional and integer orders.

STUDY OF ERROR OF APPROXIMATION OF CONJUGATE FOURIER SERIES IN WEIGHTED CLASS BY ALMOST RIESZ MEANS
, 2020 The present work is aimed to study error (or degree) of approximation of a function g̃, conjugate to 2π-periodic function g, belonging to weighted W (Lp, ξ (t)) (p ≥ 1) by almost Riesz means.

On the degree of approximation by Gauss Weierstrass integrals
International Journal of Mathematics and Mathematical Sciences, Volume 23, Issue 9, Page 645-649, 2000., 2000 We obtain the degree of approximation of functions belonging to class Lip(ψ(u, v); p), p > 1 using the Gauss Weierstrass integral of the double Fourier series of f(x, y).
