The structure of group preserving operators
Davide Barbieri, Carlos Cabrelli, Diana Carbajal +2
In this paper, we prove the existence of a particular diagonalization for normal bounded operators defined on subspaces of where is a second coun…
Continuous and discrete dynamical sampling
Rocío Díaz Martín, Ivan Medri, Ursula Molter
In this paper we study the continuous dynamical sampling problem at infinite time in a complex Hilbert space . We find necessary and sufficient conditions on a bounded…
Dynamical Sampling: a view from control theory
Rocío Díaz Martín, Ivan Medri, Ursula Molter
In this contribution we establish a dictionary between terms in two different areas in order to show that many of the topics studied are common ones - just with a different termino…
Riesz bases of exponentials and the Bohr topology
Carlos Cabrelli, Kathryn Hare, Ursula Molter
We provide a necessary and sufficient condition to ensure that a multi-tile of of positive measure (but not necessarily bounded) admits a structured Riesz basis of expone…
