Abstract

In this paper we consider systems of vectors in a Hilbert space H\mathcal{H} of the form {gjk:jJ,kK}H\{g_{jk}: j \in J, \, k\in K\}\subset \mathcal{H} where JJ and KK are countable sets of indices. We find conditions under which the local reconstruction properties of such a system extend to global stable recovery properties on the whole space. As a particular case, we obtain new local-to-global results for systems of type {Ang}gG,0nL\{A^ng\}_{g\in\mathcal{G},0\leq n\leq L } arising in the dynamical sampling problem.
