Addition to V. P. Zastavnyi’s paper “Estimates for sums of moduli of blocks in trigonometric Fourier series”

详细

Results on the integrability and integrability with power weight for sums of moduli of blocks from the series Ʃ1/k sin kx are extended to the class of series Ʃb_k sin kx with coefficients b_k of a more general form.
