On the sequence of fourier coefficients by ЦТЦ.С, method

Mohanty and Nanda [2] were the First to establish a result for (C,l) i.e. C -summability of the sequence {n B (x)}. Varshney [5] established a theorenı on (N , -î--)C, * . M- r . ", n , Jî+l summability. In the preseni paper we have discussed (a pCj-summability of the sequence {n B^(x)} which inciudes the result due to Tripathi and Singh [7]. 1. Let Z Ujj be a given infinite series with the sequence of partial sums Let ||T|| = (a^ı,) be infinite triangular matrix with real eonstants. Then sequence to sequenee transformation.
