Generalized Almost Matrix Summability of Fourier Series and Its Conjugate Series

Abstract

The object of this paper is to give three specific theorems which implies authors [1] and [14] theorems on Nörlund summability of conjugate derived Fourier series and a generalization of a theorem of Iyengar on the harmonic summability of Fourier series respectively and deduce several known and new results from the theorems.
