Bivariate Maximum Product–Type Favard–Szasz–Mirakyan and Meyer–König–Zeller Operators

Journal of Mathematics, Volume 2026, Issue 1, 2026.
In the present paper, we set up the structure of the bivariate maximum product (max‐product)–type of Meyer–König and Zeller operators and Favard–Szasz–Mirakyan operators corresponding to the linear univariate counterparts. Then, we provide an error estimation for these bivariate max‐product type operators in terms of the modulus of continuity.

The Adaptive Backstepping Synchronization Control for a Kind of Variable-Order Fractional Uncertain Nonlinear Systems

Fractal and Fractional
This paper is concerned with the adaptive backstepping synchronization control for a class of variable-order (VO) fractional uncertain nonlinear system with external disturbances and a dead zone. A kind of VO fractional command filter is employed to cope

Towards the best constant in front of the Ditzian-Totik modulus of smoothness

Journal of Inequalities and Applications, 2016
We give accurate estimates for the constants K ( A ( I ) , n , x ) = sup f ∈ A ( I ) | L n f ( x ) − f ( x ) | ω σ 2 ( f ; 1 / n ) , x ∈ I , n = 1 , 2 , … , $$ K\bigl(\mathcal{A}(I), n, x\bigr)=\sup_{f\in\mathcal{A}(I)}\frac{|L_{n} f(x)-f(x)|}{\omega_ ...

Controllability and Modeling Perspectives of Tempered Ψ‐Caputo Fractional Systems

Journal of Mathematics, Volume 2026, Issue 1, 2026.
In this article, we investigated the controllability of fractional dynamical systems (FDS) involving the tempered Ψ‐Caputo fractional derivative (FD). First, we derived the solution representation for this generalized FD with the help of Laplace transform and Mittag–Leffler (M‐L) function.

Weighted Approximation by Szász–Mirakyan–Durrmeyer Operators Reproducing Exponential Functions

Mathematics
We examine a Szász–Mirakyan–Durrmeyer type operator that reproduces the functions 1 and e2ax for a fixed parameter a>0. While its exponential reproduction property has been described in the classical literature, the effect of exponential weights on its ...

Approximation results on Dunkl generalization of Phillips operators via q-calculus

Advances in Difference Equations, 2019
The main purpose of this paper is to construct q-Phillips operators generated by Dunkl generalization. We prove several results of Korovkin type and estimate the order of convergence in terms of several moduli of continuity.
