Controlled K−g−Fusion Frames in Hilbert C∗−Modules
International Journal of Analysis and Applications, 2022 Controlled frames have been the subject of interest because of its ability to improve the numerical efficiency of iterative algorithms for inverting the frame operator.

Sums of A Pair of Orthogonal Frames
Mathematics, 2019 Frames are more stable as compared to bases under the action of a bounded linear operator. Sums of different frames under the action of a bounded linear operator are studied with the help of analysis, synthesis and frame operators.

Frames and factorization of graph Laplacians [PDF]
Opuscula Mathematica, 2015 Using functions from electrical networks (graphs with resistors assigned to edges), we prove existence (with explicit formulas) of a canonical Parseval frame in the energy Hilbert space \(\mathscr{H}_{E}\) of a prescribed infinite (or finite) network ...

Generalized continuous frames for operators
Sahand Communications in Mathematical Analysis, 2019 Summary: In this note, the notion of generalized continuous \(K\)-frame in a Hilbert space is defined. Examples have been given to exhibit the existence of generalized continuous \(K\)-frames. A necessary and sufficient condition for the existence of a generalized continuous \(K\)-frame in terms of its frame operator is obtained and a characterization ...

Some relationship between G-frames and frames [PDF]
Sahand Communications in Mathematical Analysis, 2015 In this paper we proved that every g-Riesz basis for Hilbert space $H$ with respect to $K$ by adding a condition is a Riesz basis for Hilbert $B(K)$-module $B(H,K)$. This is an extension of [A. Askarizadeh,M. A.

Characterizations of Unit Darboux Ruled Surface with Quaternions
Journal of New Theory, 2023 This paper presents a quaternionic approach to generating and characterizing the ruled surface drawn by the unit Darboux vector. The study derives the Darboux frame of the surface and relates it to the Frenet frame of the base curve. Moreover, it obtains

On a Generalization of the Hilbert Frame Generated by the Bilinear Mapping
Journal of Function Spaces, 2016 The concept of b-frame which is a generalization of the frame in Hilbert spaces generated by the bilinear mapping is considered. b-frame operator is defined; analogues of some well-known results of frame theory are obtained in Hilbert spaces.

A Note on Frames in Quaternionic Hilbert Spaces [PDF]
Sahand Communications in Mathematical AnalysisIn this paper, we define a modified version of frame in quaternionic Hilbert spaces (QHS) and give a necessary condition for a block Bessel sequence in terms of a bounded right linear operator.
