Approximation of Fourier Series of a function of class by Product Means

Abstract

Lipchitz class of function had been introduced by McFadden[7}.Recently dealing with degree of approximation of Fourier series of a function of Lipchitz class Nigam[4] and Misra et al [2],[3] have established certain theorems. Extending their
