Absolute convergence of Fourier series with respect to bounded systems
S. V. Bochkarev Steklov Mathematical Institute, Academy of Sciences of the USSR
Abstract:
In this paper we prove that for the piecewise-linear unit jump approximation the sum of the moduli of the Fourier coefficients with respect to an arbitrary complete orthonormal system, which is totally bounded, has, when averaged over sections, a lower bound of order $\log N$, where $N^{-1}$ is the approximation step.
