Second-order logarithmic methods for the summability of Fourier series
Abstract In this paper, we first present the second-order Riesz and Nörlund logarithmic summation methods, followed by a class of regular summation techniques based on second-order logarithmic averages. We then examine their applications to the pointwise convergence of Fourier series for continuous and integrable functions.
