Weighted Approximation by the Goodman–Sharma-Type Operators
, 2012 P. E. Parvanov - The uniform weighted approximation errors of the Goodman–Sharma operators are characterized for functions.Равномерната теглова апроксимация с модифицирани по Гудман–Шарма опера-тори от тип на Бернщайн, Баскаков и Майер–Кьоних–Целер е ...

On approximation in generalized Zygmund class
Demonstratio Mathematica, 2019 Here, we estimate the degree of approximation of a conjugate function g˜{\tilde g} and a derived conjugate function g˜′{\tilde g'} , of a 2π-periodic function g∈Zrλg \in Z_r^\lambda , r ≥ 1, using Hausdorff means of CFS (conjugate Fourier series) and

Basc: Constrained Approximation by Semidefinite Programming
, 2016 This article details the theoretical grounds for a semidefinite-programming-based method that computes best approximants by splines under some general constraints and relative to several function norms, notably the max-norm.

Density of Polynomials in the L^2 Space on the Real and the Imaginary Axes and in a Sobolev Space [PDF]
, 2009 2000 Mathematics Subject Classification: 41A10, 30E10, 41A65.In this paper we consider an L^2 type space of scalar functions L^2 M, A (R u iR) which can be, in particular, the usual L^2 space of scalar functions on R u iR.

Simulations and analysis of underwater acoustic wave propagation model based on Helmholtz equation
Applied Mathematics in Science and EngineeringIn this study, we explore the effectiveness of elliptic partial differential equations (PDEs) in two and three dimensional space based on Helmholtz equation for simulations of acoustic sound in a very complex environment of propagation. For this purpose,
