U.K. Misra, Subrata K Sahu, D. Acharya, P.C. Nayak

Abstract


Lipchitz class of function had been introduced by McFadden [8]. Recently dealing with degree of approximation of Fourier series of a function of Lipchitz class Nigam [12] and Misra et al.[9,10,11] have established certain theorems. Extending their results, in this paper a theorem on degree of approximation of a function by product summability has been established.


Keywords
