Hyperbolic Tangent Like Relied Banach Space Valued Neural Network Multivariate Approximations

open access: yesAnnals of the West University of Timisoara: Mathematics and Computer Science, 2023
Here we examine the multivariate quantitative approximations of Banach space valued continuous multivariate functions on a box or ℝN , N ∈ ℕ, by the multivariate normalized, quasi-interpolation, Kantorovich type and quadrature type neural network ...

Iterates of q-Bernstein operators on triangular domain with all curved sides

open access: yesDemonstratio Mathematica, 2022
In this article, Phillips-type Bernstein operators (ℬm,qtF)(t,s)({{\mathcal{ {\mathcal B} }}}_{m,q}^{t}F)\left(t,s) and (ℬn,qsF)(t,s)({{\mathcal{ {\mathcal B} }}}_{n,q}^{s}F)\left(t,s), their products, and Boolean sum based on q-integer have been studied

Korovkin type approximation theorems in weighted spaces via power series method [PDF]

open access: yes, 2018
In this paper we consider power series method which is also member of the class of all continuous summability methods. We study a Korovkin type approximation theorem for a sequence of positive linear operators acting from a weighted space Cρ1 into a ...

About the B-concavity of functions with many variables

open access: yesAnalele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2023
The paper deals with the study of the property of B-concavity and BB concavity in the bi-dimesional case and with the relation between these properties and the Bernstein operators defined on a simplex.

On Better Approximation of the Squared Bernstein Polynomials [PDF]

open access: yesمجلة جامعة الانبار للعلوم الصرفة, 2022
The present paper is defined a new better approximation of the squared Bernstein polynomials. This better approximation has been built on a positive function  defined on the interval [0,1] which has some properties.

Approximation of conic sections by weighted Lupaş post-quantum Bézier curves

open access: yesDemonstratio 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.

Rate of convergence of bounded variation functions by a Bézier‐Durrmeyer variant of the Baskakov operators

open access: yesInternational Journal of Mathematics and Mathematical Sciences, Volume 2004, Issue 9, Page 459-468, 2004., 2004
We consider a Bézier‐Durrmeyer integral variant of the Baskakov operators and study the rate of convergence for functions of bounded variation.

Dunkl analogue of Szász-mirakjan operators of blending type

open access: yesOpen Mathematics, 2018
In the present work, we construct a Dunkl generalization of the modified Szász-Mirakjan operators of integral form defined by Pǎltanea [1]. We study the approximation properties of these operators including weighted Korovkin theorem, the rate of ...

A note on integral modification of the Meyer‐König and Zeller operators

open access: yesInternational Journal of Mathematics and Mathematical Sciences, Volume 2003, Issue 31, Page 2003-2009, 2003., 2003
Guo (1988) introduced the integral modification of Meyer‐Kö nig and Zeller operators Mˆn and studied the rate of convergence for functions of bounded variation. Gupta (1995) gave the sharp estimate for the operators Mˆn. Zeng (1998) gave the exact bound and claimed to improve the results of Guo and Gupta, but there is a major mistake in the paper of ...
