Abstract

FOURiER SERiLERiNiN MUTLAK HAUSDORFF TOPLANABiLMESi

Bu çalısmada, (μ n ) dizisi için (−p ,p ) aralığında Lebesgue anlamında integrallenebilen 2p periyotlu f fonksiyonunun Fourier serisinin n H,μ toplanabilmesi ile ilgili iki teorem ispatlanmıstır.

ABSOLUTE HAUSDORFF SUMMABILITY OF THE FOURIER SERIES

In this study, two theorems with respect to n H,μ summability of Fourier series of f
function which has 2p period and integrable in the mean of Lebesgue in the interval (−p ,p ) for sequence ( ) n μ , are proved .
