Query: Some Results about Frames   In this paper we discuss some topics related to the general theory of frames.
In particular we focus our attention to the existence of different
'reconstruction formulas' for a given vector of a certain Hilbert space and to
some refinement of the perturbative approach for the computation of the dual
frame.
