On the Sum of g-Frames and Their Stability in Hilbert Spaces

Mediterranean Journal of Mathematics, 2023
The frame theory has roots in harmonic and functional analysis, operator theory, linear algebra, and matrix theory. The frame condition was first described by \textit{R. J. Duffin} and \textit{A. C. Schaeffer} [Trans. Am. Math. Soc. 72, 341--366 (1952; Zbl 0049.32401)] in a 1952 article on nonharmonic Fourier series as a way of computing the ...

New properties of phase-retrievable g-frames and exact phase-retrievable g-frames

Linear and Multilinear Algebra, 2020
The primary purpose of this paper is to discuss phase-retrievable g-frames and exact phase-retrievable g-frames. Firstly, some characterizations of phase-retrievable g-frames are discussed.

CONSTRUCTION OF DUAL g-FRAMES FOR CLOSED SUBSPACES

International Journal of Wavelets, Multiresolution and Information Processing, 2011
In this paper, we introduce dual g-frames for a closed subspace in a separable Hilbert space and also give a characterization. Generally dual g-frames for a closed subspace are non-commutative. Therefore, we construct dual g-frames for closed subspaces from two aspects and give the corresponding formulas, respectively. Finally, we give a necessary and

Some properties on G-frames

2010 International Conference on Wavelet Analysis and Pattern Recognition, 2010
Frames play an important role in wavelet analysis. G-fra mes are generalized frames which include ordinary frames, a nd many other recent generalization of frames. In this paper, we give several theorems to construct a large number of new G-frames from existing G-frames.

Some properties of g-frames in Banach spaces

International Journal of Wavelets, Multiresolution and Information Processing, 2018
In this paper, we introduce and study woven approximate Schauder g-frames. We show that for any two approximate Schauder g-frames, each weaving is an approximate Schauder g-frame if and only if there is a uniform constant [Formula: see text] such that every weaving is a C-approximate Schauder g-frame, and we obtain some perturbation results for ...

Some Results on Fusion Frames and g-Frames

Results in Mathematics, 2018
The author studies some properties of fusion frames and \(g\)-frames in relation to frames. She introduces the notion of upper and lower redundancies of \(g\)-frames and shows that some of the desirable results known about the redundancies on frames and fusion frames carry over \(g\)-frames.
