(INDIA) Mandsaur Institute of Pharmacy, Mandsour - 458001 (INDIA) <p style="text-align: justify;">In this paper, we shall prove general theorems which contain two theorems on the absolute generalized N&ouml;rlund summability of the orthogonal expansion. In 2002, B.E. Rhoades and Ekrem Savas⁶ obtained an absolute N&ouml;rlund summability of Fourier series. In this paper, we obtain the comparable result of ⁶ with N&ouml;rlund summability of the Fourier orthogonal expansion.</p> https://www.ultrascientist.org/paper/1258/ absolute Nu00f6rlund summability orthogonal expansion
