Abstract
We obtain sufficient conditions for functions defined on \(p\)-adic linear space providing the weighted integrability of their Fourier transforms. The Bernstein-Szasz type conditions connected with moduli of smoothness are sharp in a certain sense. As a corollary we deduce recent results of S. S. Platonov. Also we prove Zygmund type tests for integrability of functions having bounded \(s\)-fluctuation and belonging to a Hölder class.
