Complete interpolating sequences for Fock type spaces
Karim Kellay, Youssef Omari
We obtain a characterization of complete interpolating sequences in a class of Fock-type spaces with radial weights for which such sequences exist. Our criterion is formulated in t…

On Wiener's Lemma on locally compact abelian groups
Philippe Jaming, Karim Kellay, Rolando Perez
We establish a general form of Wiener's lemma for measures on locally compact abelian (LCA) groups by using Fourier analysis and the theory of F{ø}lner sequences. Our approach pro…

On L1-norms for non-harmonic trigonometric polynomials with sparse frequencies
Philippe Jaming, Karim Kellay, Chadi Saba +1
In this paper we show that, if an increasing sequence has gaps going to infinity when , then for every …
