The degree of approximation by Hausdorff means of a conjugate Fourier series

Sergiusz Kęska

Abstract


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.

Keywords


Hausdorff matrix; conjugate series of the Fourier series; degree of approximation
