Absolute Norlund Summability Factors for Fourier Series

It is well known that Σa _n is convergent then Σa _n is not necessarily convergent. If Σa _n is also convergent then Σa _n is said to be absolutely convergent. By this analogy absolute summability has been defined and several researchers have obtained summability factors for so many summability methods. In this paper we have obtained summability factor for Absolute Norlund Summability N,P_n of Fourier series and we have established following theorem.
