Integrability problems and Boas type results for Hartley-Bessel transforms

  • Sergey Volosivets

摘要

In the paper, we give sufficient conditions for weighted integrability of Hartley-Bessel transform of a function in terms of generalized modulus of smoothness in weighted space \(L^p\) L p on \({\mathbb {R}}\) R . For \(p=2\) p = 2 we prove the sharpness of these conditions. Boas type results connecting the growth or decay of a function in the mean and the uniform generalized smoothness properties of its Hartley-Bessel transform are established.
