Abstract
We discuss some perturbation results concerning certain pairs of sequences of vectors in a Hilbert space H and producing new sequences, which share, with the original ones, reconstruction formulas on a dense subspace of H or on the whole space. We also propose some preliminary results on the same issue, but in a distributional settings.
