Some properties of pre-quasi operator ideal of type generalized Cesáro sequence space defined by weighted means

open access: yesOpen Mathematics, 2019
Let E be a generalized Cesáro sequence space defined by weighted means and by using s-numbers of operators from a Banach space X into a Banach space Y.

Differences of Weighted Mixed Symmetric Means and Related Results

open access: yesJournal of Inequalities and Applications, 2010
Some improvements of classical Jensen's inequality are used to define the weighted mixed symmetric means. Exponential convexity and mean value theorems are proved for the differences of these improved inequalities. Related Cauchy means are also defined,

Abel-type weighted means transformations into ℓ

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2000
Let qk=(k+α    k) for α>−1 and Qn=∑k=0nqk. Suppose Aq={ank}, where ank=qk/Qn for 0≤k≤n and 0 otherwise. Aq is called the Abel-type weighted mean matrix. The purpose of this paper is to study these transformations as mappings into ℓ.

Weighted inequalities for the Bochner–Riesz means related to the Fourier–Bessel expansions [PDF]

open access: yes, 2007
We prove weighted inequalities for the Bochner–Riesz means for Fourier–Bessel series with more general weights w(x) than previously considered power weights.

Approximation by weighted means of Walsh-Fourier series

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1996
We study the rate of approximation to functions in Lp and, in particular, in Lip(α,p) by weighted means of their Walsh-Fourier series, where α>0 and 1≤p≤∞.

Generalizing the Alpha-Divergences and the Oriented Kullback–Leibler Divergences with Quasi-Arithmetic Means

open access: yesAlgorithms, 2022
The family of α-divergences including the oriented forward and reverse Kullback–Leibler divergences is often used in signal processing, pattern recognition, and machine learning, among others.

Notes on Weighted Mean and Median [PDF]

open access: yesTamap Journal of Mathematics and Statistics, 2018
The paper investigates the application and generalization of the weighted mean and median by using continuous and convex functions. The paper offers a clear and systematic approach to the notion of weighted medians. As a result, essential characteristics of weighted medians are presented better.

APPROXIMATION BY LINEAR MEANS OF FOURIER SERIES AND REALIZATION FUNCTIONALS IN WEIGHTED ORLICZ SPACES

open access: yesПроблемы анализа, 2022
Using one-sided Steklov means, we introduce a new modulus of smoothness in weighted Orlicz spaces and state its equivalence with a special 𝐾-functional. We prove Stechkin-Nikol’skii-type inequality for trigonometric polynomials and direct estimates for
