Shape‐preserving multivariate polynomial approximation in C[−1,1]m

International Journal of Mathematics and Mathematical Sciences, Volume 2004, Issue 7, Page 325-333, 2004., 2004
We construct multivariate polynomials attached to a function f of m variables, m ≥ 2 , which approximate f with Jackson‐type rate involving a multivariate Ditzian‐Totik ω2φ‐modulus and preserve some natural kinds of multivariate monotonicity and convexity of function.

Error Estimation for Shifted q‐Szász–Kantorovich Operators and Their Numerical Properties

Journal of Mathematics, Volume 2026, Issue 1, 2026.
This paper introduces a novel class of q‐Szász–Mirakjan–Kantorovich operators defined with shifted sequences. Utilizing the basic principles of q‐calculus, we design the King‐type fundamental construction of q‐Szász–Mirakjan–Kantorovich operators and derive their moments and central moments.

Refined Estimates for the Equivalence Between Ditzian-Totik Moduli of Smoothness and K-Functionals [PDF]

The aim of this note is to study the magnitude of the constants in the equivalence between the first and secondorder Ditzian-Totik moduli of smoothness and related K-functionals.

Approximation Properties of Ibragimov-Gadjiev-Durrmeyer Operators on Lp (ℝ+)

Demonstratio Mathematica, 2017
We deal with the approximation properties of a new class of positive linear Durrmeyer type operators which offer a reconstruction of integral type operators including well known Durrmeyer operators.

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

, 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.

A study on blending-type approximation through α-Szász–Durrmeyer-type operators

Journal of Taibah University for Science
We propose a Durrmeyer-type extension of the [Formula: see text]-Szász-Mirakyan operators. By employing a unified approach based on the Lipschitz kind maximal function, weighted function spaces, and the Ditzian–Totik modulus of smoothness, we obtain ...
