Resumen:
The definition of dual fusion frame presents technical problemsrelated to the domain of the synthesis operator. The notion commonlyused is the analogous to the canonical dual frame. Here a new concept ofdual is studied in infinite-dimensional separable Hilbert spaces. It extendsthe commonly used notion and overcomes these technical difficulties. Weshow that with this definition in many cases dual fusion frames behavesimilar to dual frames. We exhibit examples of non-canonical dual fusionframes.
