DEGREE OF APPROXIMATION IN THE GENERALIZED LIPSCHITZ CLASS VIA (E, q)A- PRODUCT SUMMABILITY MEANS OF FOURIER SERIES

Özet

Dealing with degree of approximation of Fourier series of functions of Lipchitz classes, some results have been established by Nigam [15] and Misra et al. [17]. In this paper, we have established a new theorem based on (E, q)A- product summability mean in order to estimate the degree of approximation of a function f ∈ Lip(ξ(t), r)
