I. M. Vasil'ev St. Petersburg Department of Steklov Mathematical Institute of Russian Academy of Sciences, St. Petersburg, Russia
Abstract:
In this paper, we announce a result that generalizes the first Beurling–Malliavin theorem. In other words, we give a new sufficient condition on a function guaranteeing that it belongs to the Beurling–Malliavin class of majorants. It is also shown that the main result of this article is sharp in many senses.
Keywords:
Fourier transform, spectrum, Hilbert transform, logarithmic integral, Beurling–Malliavin theorem.
