The Rate of Convergence for Linear Shape-Preserving Algorithms

100%

Boytsov D., Sidorov S.

Concrete Operators

2015

tom 2

nr 1

We prove some results which give explicit methods for determining an upper bound for the rate of approximation by means of operators preserving a cone. Thenwe obtain some quantitative results on the rate of convergence for some sequences of linear shape-preserving operators.

On the approximation of conjugate functions from \(L^{p}\) by some special matrix means of conjugate Fourier series

100%

Krantz R., Rzepka A.

Commentationes Mathematicae

2014

tom 54

nr 2

The results corresponding to some theorems of W. Łenski and B. Szal are shown. From the presented pointwise results the estimates on norm approximation are derived. Some special cases as corollaries are also formulated.

nr 2

The purpose of this paper is to analyze the degree of approximation of a function \(\overline f\) that is a conjugate of a function \(f\) belonging to the Lipschitz class by Hausdorff means of a conjugate series of the Fourier series.
