An appropriate representation space for controlled G-frames
Maryam Forughi, Elnaz Osgooei, Asghar Rahimi +1
In this paper, motivating the range of operators, we propose an appropriate representation space to introduce synthesis and analysis operators of controlled g-frames and discuss th…
Gram matrix associated to controlled frames
Elnaz Osgooei, Asghar Rahimi
Controlled frames have been recently introduced in Hilbert spaces to improve the numerical efficiency of interactive algorithms for inverting the frame operator. In this paper, unl…
Compare and contrast between duals of fusion and discrete frames
Elnaz Osgooei, Ali Akbar Arefijamaal
Fusion frames are valuable generalizations of discrete frames. Most concepts of fusion frames are shared by discrete frames. However, the dual setting is so complicated. In particu…
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…
