Abstract:
In this paper, first we develop the duality concept for g-Bessel sequences and Bessel fusion sequences in Hilbert spaces. We obtain some results about dual, pseudo-dual and approximate dual of frames and fusion frames. We also expand every g-Bessel sequence to a frame by summing some elements. We define the restricted isometry property for g-frames and generalize some results from (B. G. Bodmann et al, Fusion frames and the restricted isometry property, Num. Func. Anal. Optim. ۳۳ (۲۰۱۲) ۷۷۰-۷۹۰) to g-frame situation. Finally we study the stability of g-frames under erasure of operators.
