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 newconcept of dual is studied in infinite-dimensional separable Hilbertspaces. It extends the commonly used notion and overcomes thesetechnical difficulties. We show that with this definition in manycases dual fusion frames behave similar to dual frames. We presentexamples of non-canonical dual fusion frames.
