摘要：
We adopt here an extended version of the absolute Nevanlinna summability and apply it to study Fourier series of functions of bounded variations. The absolute Riesz summability \R, n, gamma\, gamma greater than or equal to 0, which is equivalent to the absolute Cesaro summability IC, yl, is obtainable from the Nevanlinna summability. As such from the theorems proved here we deduce some results on the absolute Cesaro summability of Fourier series. Some of these results are new while some others improve upon known theorems.
