  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 qgeq 1$. Here we have obtained sufficiency conditions for the absolute convergence of such series if $ f$ is of $ bigwedge BV^{(p)}$ locally. We have also obtained a beautiful interconnection between lacunary and non-lacunary Fourier series.;
