Framings and dilations

, 2013
The notion of framings, recently emerging in P. G. Casazza, D. Han, and D. R. Larson, Frames for Banach spaces, in {\em The functional and harmonic analysis of wavelets and frames} (San Antonio, TX, 1999), {\em Contemp. Math}.

Continuous k-frames and their duals

, 2019
k-frames were recently introduced by Gavruta in Hilbert spaces to study atomic systems with respect to a bounded linear operator. A continuous frame is a family of vectors in Hilbert space which allows reproductions of arbitrary elements by continuous super positions. We construct a continuous k-frame, so called ck-frame along with an atomic system for

Dilations of *-frames and their operator duals

Filomat, 2018
Theory of frame has been extended from Hilbert spaces to various spaces, specially, to Hilbert C*-modules. The paper introduces operator duals for frames with C*-valued bounds in Hilbert C*-modules. It is shown that operator duals for frames (*-frames) share several useful properties with ordinary duals.

Dual Frame Completion Problem

In this paper we present the construction of an exact dual frame under specific structural assumptions posed on the dual frame. When given a frame $F$ for a finite dimensional Hilbert space, and a set of vectors $H$ that is assumed to be a subset of a dual frame of $F$, we answer the following question: Which dual frame $G$ for $F$ - if it exists ...
