The concept of [Formula: see text]-frames was recently introduced by Găvruta7 in Hilbert spaces to study atomic systems with respect to a bounded linear operator. Let [Formula: see text] be a unital [Formula: see text]-algebra, [Formula: see text] be finitely or countably generated Hilbert [Formula: see text]-modules, and [Formula: see text] be adjointable operators from [Formula: see text] to [Formula: see text]. In this paper, we study a class of [Formula: see text]-bounded operators and [Formula: see text]-operator frames for [Formula: see text]. We also prove that the pseudo-inverse of [Formula: see text] exists if and only if [Formula: see text] has closed range. We extend some known results about the pseudo-inverses acting on Hilbert spaces in the context of Hilbert [Formula: see text]-modules. Further, we also present some perturbation results for [Formula: see text]-operator frames in [Formula: see text].
Dynamical sampling deals with frames of the form {T n ϕ} ∞ n=0 , where T ∈ B(H) belongs to certain classes of linear operators and ϕ ∈ H. The purpose of this paper is to investigate a new representation, namely, Fibonacci representation of sequences {fn} ∞ n=1 in a Hilbert space H; having the form fn+2 = T (fn + fn+1) for all n 1 and a linear operator T : span{fn} ∞ n=1 → span{fn} ∞ n=1 . We apply this kind of representations for complete sequences and frames. Finally, we present some properties of Fibonacci representation operators.
In this paper, we introduce pg-continuous frames and study the operators associated with a give pg-continuous frames. We also show many useful properties with corresponding notions, pg-continuous frames and pg-frames in Banach space.
Due to the importance of frame representation by a bounded operator in dynamical sampling, researchers studied the frames of the form {T i−1 f } i∈N , which f belongs to separable Hilbert space H and T ∈ B(H), and investigated the properties of T . Given that g-frames include the wide range of frames such as fusion frames, the main purpose of this paper is to study the characteristics of the operator T for g-frames of the form {ΛT i−1 ∈ B(H, K) : i ∈ N}.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
