Dual Frame Completion Problem
Roza Aceska, Yeon Hyang Kim, Sivaram K. Narayan
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 for a finite dimensional Hilb…
Complex Symmetric Composition Operators on
Sivaram K. Narayan, Daniel Sievewright, Derek Thompson
In this paper, we find complex symmetric composition operators on the classical Hardy space whose symbols are linear-fractional but not automorphic. In doing so, we answer a recent…
Minimal scalings and structural properties of scalable frames
Alice Chan, Rachel Domagalski, Yeon Hyang Kim +3
For a unit-norm frame in , a scaling is a vector such that is a Parseval frame in $…
On Structural Decompositions of Finite Frames
Alice Z. -Y. Chan, Martin S. Copenhaver, Sivaram K. Narayan +2
A frame in an -dimensional Hilbert space is a possibly redundant collection of vectors that span the space. A tight frame is a generalization of an orth…
Factor posets of frames and dual frames in finite dimensions
Kileen Berry, Martin S. Copenhaver, Eric Evert +4
We consider frames in a finite-dimensional Hilbert space where frames are exactly the spanning sets of the vector space. A factor poset of a frame is defined to be a collection of…
Maximum Robustness and Surgery of Frames in finite dimensions
Martin S. Copenhaver, Yeon Hyang Kim, Cortney Logan +3
We consider frames in a finite-dimensional Hilbert space Hn where frames are exactly the spanning sets of the vector space. We present a method to determine the maximum robustness…
