Connectivity and Irreducibility of Algebraic Varieties of Finite Unit Norm Tight Frames
Jameson Cahill, Dustin G. Mixon, Nate Strawn
In this paper, we settle a long-standing problem on the connectivity of spaces of finite unit norm tight frames (FUNTFs), essentially affirming a conjecture first appearing in [Dyk…
Tight and random nonorthogonal fusion frames
Jameson Cahill, Peter G. Casazza, Martin Ehler +1
First we show that tight nonorthogonal fusion frames a relatively easy to com by. In order to do this we need to establish a classification of how to to wire a self adjoint operato…
Phase Retrieval By Projections
Jameson Cahill, Peter G. Casazza, Jesse Peterson +1
The problem of recovering a vector from the absolute values of its inner products against a family of measurement vectors has been well studied in mathematics and engineering. A ge…
Saving phase: Injectivity and stability for phase retrieval
Afonso S. Bandeira, Jameson Cahill, Dustin G. Mixon +1
Recent advances in convex optimization have led to new strides in the phase retrieval problem over finite-dimensional vector spaces. However, certain fundamental questions remain:…
A note on scalable frames
Jameson Cahill, Xuemei Chen
We study the problem of determining whether a given frame is scalable, and when it is, understanding the set of all possible scalings. We show that for most frames this is a relati…
