Properties of bounded representations for -frames
Fatemeh Ghobadzadeh, Yavar Khedmati, Javad Sedghi Moghaddam
Due to the importance of frame representation by a bounded operator in dynamical sampling, researchers studied the frames of the form , which b…
Fibonacci representations of sequences in Hilbert spaces
J. Sedghi Moghaddam, A. Najati, Y. Khedmati
Dynamical sampling deals with frames of the form , where belongs to certain classes of linear operators and . The pur…
Dynamical sampling: mixed frame operators, representations and perturbations
Ehsan Rashidi, Abbas Najati, Elnaz Osgooei
Motivated by recent progress in operator representation of frames, we investigate the frames of the form for , and answer question…
More sums of Hilbert frames
A. Najati, M. R. Abdollahpour, E. Osgooei +1
In this paper we have some new results on sums of Hilbert space frames and Riesz bases. We also have a correction for some results in "S. Obeidat et al., Sums of Hilbert space fram…
Approximately Quadratic Mappings on Restricted Domains
Abbas Najati And Soon-Mo Jung
In this paper, we introduce a generalized quadratic functional equation where are nonzero real numbers with We show th…
