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, β₯ , β₯ G 0, which is equivalent to the absolute Cesaro < < summability C, β₯ , is obtainable from the Nevanlinna su
