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

On weighted approximation with Jacobi weights [PDF]
Journal 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.

The Weighted Ambrosio--Tortorelli Approximation Scheme [PDF]
SIAM 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]
Sustainability, 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.

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

Weighted best local L approximation
Journal of Approximation Theory, 1984 For a weight w with some conditions near the origin the limit of the error \(\epsilon^{-n-1}\{f(\epsilon t)-P_{w,\epsilon}f(\epsilon t)\}\), where \(P_{w,\epsilon}f\) is the weighted best \(L^ p_{w,\epsilon}\) approximation of the function f in a class \(t^ p_{m,w}\), analogous to those considered by Calderón and Zygmund, is characterized. The limit is

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