Degree of Approximation of Functions f ∈ Hω Class by the (Np E1) Means in the Hölder Metric

International Journal of Mathematics and Mathematical Sciences, 2014
A new estimate for the degree of approximation of a function class by means of its Fourier series has been determined. Here, we extend the results of Singh and Mahajan (2008) which in turn generalize the result of Lal and Yadav (2001).

The Relation Between the Degree of Monotone Approximation and the Degree of Unconstrained Approximation

Mustansiriyah Journal of Pure and Applied Sciences, 2023
Many researchers related to the degree of unconstrained approximation to  constrained approximation,  and proved the inequality: For a continuous  function  on a closed interval we have                                                where  is a positive constant.

DEGREE OF APPROXIMATION BY PERIODIC NEURAL NETWORKS [PDF]

Korean Journal of Mathematics, 2014
Summary: We investigate an approximation order of a continuous \(2 \pi \)-periodic function by periodic neural networks. By using the De La Vallée Poussin sum and the modulus of continuity, we obtain a degree of approximation by periodic neural networks.

The approximation of bivariate Chlodowsky-Szász-Kantorovich-Charlier-type operators

Journal of Inequalities and Applications, 2017
In this paper, we introduce a bivariate Kantorovich variant of combination of Szász and Chlodowsky operators based on Charlier polynomials. Then, we study local approximation properties for these operators.

Asymptotic behavior of solutions to difference equations in Banach spaces

Electronic Journal of Qualitative Theory of Differential Equations, 2021
We investigate the asymptotic properties of solutions to higher order nonlinear difference equations in Banach spaces. We introduce a new technique based on a vector version of discrete L'Hospital's rule, remainder operator, and the regional topology on ...

Quantumness’ Degree of Thermal Optics’ Approximations

Symmetry, 2022
We assess the degree of quantumness of the P, Q, and W quantum optics’ approximations in a thermal context governed by the canonical ensemble treatment. First, we remint the reader of the bridge connecting quantum optics with statistical mechanics using the abovementioned approximations at the temperature T.

Approximation of signals (functions) belonging to certain Lipschitz classes by almost Riesz means of its Fourier series

Journal of Inequalities and Applications, 2016
To start with, signals are dealt with as functions of one variable and images are shown by elements of two variables. The investigation of these ideas is directly related to the transpiring area of information technology.
