Robust Dimension Reduction, Fusion Frames, and Grassmannian Packings
Gitta Kutyniok, Ali Pezeshki, Robert Calderbank +1
We consider estimating a random vector from its noisy projections onto low dimensional subspaces constituting a fusion frame. A fusion frame is a collection of subspaces, for which…
A Decomposition Theorem for frames and the Feichtinger Conjecture
Peter G. Casazza, Gitta Kutyniok, Darrin Speegle +1
In this paper we study the Feichtinger Conjecture in frame theory, which was recently shown to be equivalent to the 1959 Kadison-Singer Problem in -Algebras. We will show th…
A fundamental identity for Parseval frames
R. Balan, P. G. Casazza, D. Edidin +1
In this paper we establish a suprising fundamental identity for Parseval frames in a Hilbert space. Several variations of this result are given, including an extension to general f…
Frames of subspaces
Peter G. Casazza, Gitta Kutyniok
One approach to ease the construction of frames is to first construct local components and then build a global frame from these. In this paper we will show that the study of the re…
