Dynamical sampling, derivatives, and interpolation formulas in the Paley--Wiener space

Abstract

In this paper we present a criteria to obtain interpolations formulas in terms of the sequence ${\left(\{T_n(f)(Nm)\}{\}}_{m\in \mathbb{Z}}\right)}_{n=1}^N$, where $f$ are functions whose Fourier transform is supported in $[-1/2,1/2]$, and $T_n$ are certain Fourier multiplier operators. We also discuss applications and also prove that our results recover several classical formulas.
