Application of Nevanlinna's Method in Approximation of functions

Resumen

In the recent past, while a galaxy of researchers were contributing immensely towards the degree of approximation of functions, quite a few significant results had been published by another galaxy of researchers using Nevanlinna's method. Looking at the growing interest of approximation of functions, we in this paper have studied the degree of approximation of Fourier series of functions in Besov Space using Nevanlinna's mean.
