  Abstract:

Let $ f$ be a $ 2pi$ periodic function in $ L^1[0,2pi]$ and $ sum_{k=-infty}^infty widehat{f} (n_k) e^{in_kx}$ be its Fourier series with `small' gaps $ n_{k+1}-n_kgeq qgeq1$. Here we obtain a sufficiency condition for the convergence of the series $ sum_{kin Z}mid widehat{f} (n_k)mid^beta$ (0 ;
