Resumen:
We consider the notion of nite dimensional reconstructions systems (RS´s), whichincludes the fusion frames as projective RS´s. We study erasures, some geometricalproperties of these spaces, the spectral picture of the set of all dual systems of a xedRS, the spectral picture of the set of RS operators for the projective systems with xedweights and the structure of the minimizers of the joint potential in this setting. Wegive several examples.
