A strong converse inequality for the iterated Boolean sums of the Bernstein operator

, 2022
We establish a two-term strong converse estimate of the rate of approximation by the iterated Boolean sums of the Bernstein operator. The characterization is stated in terms of appropriate moduli of smoothness or K-functionals.

On the generalized Mellin integral operators

Demonstratio Mathematica
In this study, we give a modification of Mellin convolution-type operators. In this way, we obtain the rate of convergence with the modulus of the continuity of the mmth-order Mellin derivative of function ff, but without the derivative of the operator ...

Approximation properties of Kantorovich type q-Balázs-Szabados operators

Demonstratio Mathematica, 2019
In this paper, we introduce a new kind of q-Balázs-Szabados-Kantorovich operators called q-BSK operators. We give a weighted statistical approximation theorem and the rate of convergence of the q-BSK operators.

Estimates for Durrmeyer-type exponential sampling series in Mellin-Orlicz spaces

Demonstratio Mathematica
This study examines Durrmeyer-type exponential sampling series to obtain a quantitative estimate by using the concept of the logarithmic modulus of smoothness defined with the help of a suitable modular functional on Mellin-Orlicz spaces.

Rate of pole detection using Padé approximants to polynomial expansions

Demonstratio Mathematica
Padé approximations constructed from orthogonal and Faber polynomials on some compact set EE serve as tools to detect poles of an approximated function around the set EE.

The combined Shepard operator of inverse quadratic and inverse multiquadric type

, 2022
Starting with the classical, the modified and the iterative Shepard methods, we construct some new Shepard type operators, using the inverse qua- dratic and the inverse multiquadric radial basis functions.
