Recovering a function from its trigonometric integral
T. A. Sworowska M. V. Lomonosov Moscow State University, Faculty of Mechanics and Mathematics
Abstract:
The approximate symmetric Henstock-Kurzweil integral is shown as solving the problem of the recovery of a function from its trigonometric integral. This being so, we generalize Offord's theorem, which is an analogue of de la Vallée Poussin's theorem for trigonometric series. A new condition for a function to be representable by a singular Fourier integral is also obtained.

Keywords:
trigonometric integral, approximate symmetric integral, Preiss-Thomson theorem, Offord's theorem, singular Fourier integral.
