Matrix summability of a factored Fourier series

This paper reports a result for proving a triangular matrix summability of a factored Fourier series by extending the theorem on Nörlund summability of a factored Fourier series att =x when ?(t)∈B.V in (0, π) due to Singh 4] (Indian J. Math. 9 227–236). The result generalizes the theorem of Varshney 5] (Proc. Am. Math. Soc. 10, 784–789) and that of Singh.
