On approximation of the rate of convergence of Fourier series in the generalized Hölder metric by Deferred Nörlund mean

In this paper, we have studied an estimate of the rate of convergence of Fourier series in the generalized Holder metric \(H_{L_{r}}^{(\omega )}\) space by using deferred Norlund mean and established some new results. Our results are more advanced that generalize and unify many other results available in the literature.
