In this paper we present two applications of a Stability Theorem of Hilbert frames to nonharmonic Fourier series and wavelet Riesz basis. The first result is an enhancement of the Paley-Wiener type co...

Matei and Meyer proved that ‘simple quasicrystals’ are universal sets of sampling and interpolation for signals with a band-limited spectrum. We ask if the corresponding exponential system is a univer...
