A CLASS OF FUNCTIONS AND THEIR DEGREE OF APPROXIMATION BY ALMOST (N,p,α) METHOD
Main Article Content
Abstract
Qureshi [6] proved a theorem for the degree of approximation of a periodic function ˉf, conjugate to a 2π-periodic function f and belonging to the class Lip θ, by almost matrix mean of its conjugate series. The above theorem was further generalized by Qureshi and Nema [8] for a function belonging to the class W(Lp,Ψ1(t)) by almost matrix mean. In the present paper we have discussed degree of approximation of above class of functions by almost (N,p,α) method.
