Landau's necessary density conditions for the Hankel transform

Luís Daniel Abreu, Afonso S. Bandeira

Research output: Contribution to journalArticlepeer-review


We will prove an analogue of Landau's necessary conditions [H.J. Landau, Necessary density conditions for sampling and interpolation of certain entire functions, Acta Math. 117 (1967) 37-52] for spaces of functions whose Hankel transform is supported in a measurable subset S of the positive semi-axis. As a special case, necessary density conditions for the existence of Fourier-Bessel frames are obtained.
