Stability of concentration in the Paley-Wiener space

Denis Zelent

We prove stability of concentration in the Paley-Wiener space for each fixed time-bandwidth product. The concentration deficit controls the squared $L^{2} (R)$ -distance from a…

A Note on the Norm of the Embedding of $PW^{2}$ into $PW^{q}$

Iñaki Garrido, Filippo Persico, Denis Zelent

We improve the currently best known bound for the norm of the embedding of $P W^{2}$ into $P W^{q}$ for all $q > 2$ . We show that our bound is asymptotically optimal as $q \to \infty$ . Our…

Extreme and exposed points of shift-invariant spaces generated by Gaussian kernel and hyperbolic secant

Markus Valås Hagen, Alexander Ulanovskii, Denis Zelent +1

We characterize the extreme and exposed points of the unit ball (with respect to the $L^{1}$ -norm) in the shift-invariant space generated by the Gaussian function, as well as in the…
