On Excesses and Duality in Woven Frames

Elahe Agheshteh Moghaddam, Ali Akbar Arefijamaal

Weaving frames in separable Hilbert spaces have been recently introduced by Bemrose et al. to deal with some problems in distributed signal processing and wireless sensor networks.…

Representation of Operators Using Fusion Frames

Peter Balazs, Mitra Shamsabadi, Ali Akbar Arefijamaal +1

For finding the numerical solution of operator equations in many applications a decomposition in subspaces is needed. Therefore, it is necessary to extend the known method of matri…

Weaving Hilbert Space Frames and Duality

Fahimeh Arabyani Neyshaburi, Ali Akbar Arefijamaal

Weaving Hilbert space frames have been introduced recently by Bemrose et al. to deal with some problems in distributed signal processing. In this paper, we survey this topic from t…

Dual and multiplier of -fusion frames

Mitra Shamsabadi, Ali Akbar Arefijamaal, Ghadir Sadeghi

In this paper, we introduce the concept of -fusion frames and propose the duality for such frames. The relation between the local frames of -fusion frames with their dual is…

Some results of -frames and their multipliers

Ali Akbar Arefijamaal, Mitra Shamsabadi

K-frames are strongly tools for the reconstruction elements from the range of a bounded linear operator K on a separable Hilbert space H. In this paper, we study some properties of…

U-cross Gram matrices and their invertibility

Peter Balazs, Mitra Shamsabadi, Ali Akbar Arefijamaal +1

The Gram matrix is defined for Bessel sequences by combining synthesis with subsequent analysis operators. If different sequences are used and an operator U is inserted we reach so…
