Controlled g-fusion frame in Hilbert space

International Journal of Wavelets, Multiresolution and Information Processing, 2021
Fusion frame is a generalization of frame, which can analyze signals by projecting them onto multidimensional subspaces. Controlled fusion frame as generalization of fusion frame, it can improve the numerical efficiency of iterative algorithms for inverting the fusion frame operators. In this paper, we first introduce the notion of controlled g-fusion

Woven approximate Schauder g-fusion frames in Banach spaces

The Journal of Analysis, 2022
In the present paper, woven approximate Schauder \(g\)-fusion frames in Banach spaces are introduced and studied. Few results regarding these frames are obtained besides some perturbation results for the frames introduced.

Construction of g-fusion frames in Hilbert spaces

Infinite Dimensional Analysis, Quantum Probability and Related Topics, 2020
After introducing g-frames and fusion frames by Sun and Casazza, respectively, combining these frames together is an interesting topic for research. In this paper, we introduce the generalized fusion frames or g-fusion frames for Hilbert spaces and give characterizations of these frames from the viewpoint of closed range and g-fusion frame sequences ...

Iterative reconstruction of continuous g-fusion frames in Hilbert spaces

2021
In this article, the authors study continuous g-fusion frames in Hilbert spaces. The authors give some sufficient conditions for the existence of continuous g-fusion frames. Continuous g-fusion frames in finite-dimensional spaces are considered and a result is obtained.
