ON STRONG NŐRLUND SUMMABILITY OF ORTHOGONAL EXAPANSION

Sandeep Kumar Tiwari1, Dinesh Kumar Kachhara*2

Abstract


In this paper, we shall prove general theorems which contain two theorems on the Strong Nörlund summability of the orthogonal expansion.

In 1965 Sunouchi G. [9] obtained on the strong summability of orthogonal Series .and in 1967 Sunouchi G.,[10] prove the Approximation of Fourier Series and orthogonal Series
.
In this paper, we obtain the comparable result of [9] and [10] with general Strong Nörlund summability of orthogonal expansion.
