A Generalized Problem in Weighted Approximation [PDF]

open access: bronzeTransactions of the American Mathematical Society, 1924
shall be a minlimum, where f(x) is a given continuous ftinction, and e (x) is a given bounded function with a positive lower bound. The purpose of the present paper is to discuss the somewhat less simple problem of convergence that arises if the greatest lower bound of e (x) is zero.

Weighted approximation in $$\mathbb {C}$$ [PDF]

open access: yesMathematische Zeitschrift, 2019
We prove that if $\{ _j\}_j$ is a sequence of subharmonic functions which are increasing to some subharmonic function $ $ in $\mathbb{C}$, then the union of all the weighted Hilbert spaces $H( _j)$ is dense in the weighted Hilbert space $H( )$.

Approximating Power by Weights [PDF]

open access: yesSSRN Electronic Journal, 2018
Determining the power distribution of the members of a shareholder meeting or a legislative committee is a well-known problem for many applications. In some cases it turns out that power is nearly proportional to relative voting weights, which is very beneficial for both theoretical considerations and practical computations with many members.

The Best Approximation of Generalized Fuzzy Numbers Based on Scaled Metric

open access: yesJournal of Mathematics, 2022
The ongoing study has been vehemently allocated to propound an ameliorated α-weighted generalized approximation of an arbitrary fuzzy number. This method sets out to lessen the distance between the original fuzzy set and its approximation.

On weighted approximation with Jacobi weights [PDF]

open access: yesJournal of Approximation Theory, 2019
We obtain matching direct and inverse theorems for the degree of weighted $L_p$-approximation by polynomials with the Jacobi weights $(1-x)^ (1+x)^ $. Combined, the estimates yield a constructive characterization of various smoothness classes of functions via the degree of their approximation by algebraic polynomials.

On Kantorovich modification of ( p , q ) $( p,q ) $ -Baskakov operators

open access: yesJournal of Inequalities and Applications, 2016
The concern of this paper is to introduce a Kantorovich modification of ( p , q ) $( p,q ) $ -Baskakov operators and investigate their approximation behaviors. We first define a new ( p , q ) $( p,q ) $ -integral and construct the operators.

The Weighted Ambrosio--Tortorelli Approximation Scheme [PDF]

open access: yesSIAM Journal on Mathematical Analysis, 2017
The Ambrosio-Tortorelli approximation scheme with weighted underlying metric is investigated. It is shown that it -converges to a Mumford-Shah image segmentation functional depending on the weight $ dx$, where $ \in SBV( )$, and on its value $ ^-$.

Weight Approximation for Spatial Outcomes [PDF]

open access: yesSustainability, 2020
When preferences explicitly include a spatial component, it can be challenging to assign weights to geographic regions in a way that is both pragmatic and accurate. In multi-attribute decision making, weights reflect cardinal information about preferences that can be difficult to assess thoroughly in practice.

Trigonometric Approximation by Modulus of Smoothness in Lp,α (X)

open access: yesAl-Mustansiriyah Journal of Science, 2021
In this paper, we study the approximate properties of functions by means of trigonometric polynomials in weighted spaces. Relationships between modulus of smoothness of function derivatives and those of the jobs themselves are introduced. In the weighted
