On approximation of hexagonal Fourier series in the generalized Hölder metric

Abstract

Let $f$ be an $H$-periodic continuous function. The approximation order of the function $f$ by deferred Cesaro means of its hexagonal Fourier series is estimated in uniform and generalized H\"{o}lder metrics.

Keywords

• Deferred Cesàro means,generalized Hölder class,hexagonal Fourier series
