Abstract

In this paper we obtain, that if the partial sums \(\sigma_{q_{k}}(x)\) of a Franklin series converge in measure to a function \(f\), the ratio \(\frac{q_{k+1}}{q_{k}}\) is bounded and the majorant of partial sums satisfies to a necessary condition, then the coefficients of the series are restored by the function \(f\).
