Continuous k-frames and their duals

open access: yes, 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

open access: yesFilomat, 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.
