Robustness of controlled fusion frames under erasures of subspaces and the approximation operator
Reza Ahmadi, Gholamreza Rahimlou, Vahid Sadri
Controlled frames which presented to improve the numerical output of iterative algorithms for inverting the frame operator, have been introduced by Balazs and et al. Also, these fr…
Continuous k-frames and their duals
Gholamreza Rahimlou, Reza Ahmadi, Mohammad Ali Jafarizadeh +1
k-frames were recently introduced by Gavruta in Hilbert spaces to study atomic systems with respect to a bounded linear operator. A continuous frame is a family of vectors in Hilbe…
On continuous weaving fusion frames in Hilbert spaces
Vahid Sadri, Reza Ahmadi, Gholamreza Rahimlou
In this note, we first introduce the notation of weaving cfusion frames in separable Hilbert spaces. After reviewing the conditions for maintaining the weaving c-fusion frames unde…
Generalized fusion frames in Hilbert spaces
Vahid Sadri, Gholamreza Rahimlou, Reza Ahmadi +1
After introducing g-frames and fusion frames by Sun and Casazza, combining these frames together is an interesting topic for research. In this paper, we introduce the generalized f…
Some identities and inequalities for g-fusion frames
Ramazan Zarghami, Vahid Sadri, Reza Ahmadi
G-fusion frames which are obtained from the combination of g-frames and fusion frames were recently introduced for Hilbert spaces. In this paper, we present a new identity for g-fr…
Weighted Riesz bases in g-fusion frames and their perturbation
Gholamreza Rahimlou, Vahid Sadri, Reza Ahmadi
In this paper, we introduce orthonoramal and Riesz bases for g-fusion frames and will show that the weights have basic roles. Next, we prove an effective theorem between frames and…
Construction of k-g-fusion frames and their duals in Hilbert spaces
Vahid Sadri, Reza Ahmadi, Asghar Rahimi
Frames for operators or k-frames were recently considered by Gavruta (2012) in connection with atomic systems. Also generalized frames are important frames in the Hilbert space of…
Some properties of Controlled Fusion Frames
Habib shakoory, Reza Ahmadi, Naghi Behzadi +1
Controlled frames in Hilbert spaces have been introduced by Balazs, Antoine and Grybos to improve the numerical output of in relation to algorithms for inverting the frame operator…
