Riesz Outer Product Hilbert Space Frames: Quantitative Bounds, Topological Properties, and Full Geometric Characterization
Peter G. Casazza, Eric Pinkham, Brian Tuomanen
Outer product frames are important objects in Hilbert space frame theory. But very little is known about them. In this paper, we make the first detailed study of the family of oute…
Phase retrieval and norm retrieval
Saeid Bahmanpour, Jameson Cahill, Peter G. Casazza +2
Phase retrieval has become a very active area of research. We will classify when phase retrieval by Parseval frames passes to the Naimark complement and when phase retrieval by pro…
Consequences of the Marcus/Spielman/Stivastava solution to the Kadison-Singer Problem
Peter G. Casazza
It is known that the famous, intractible 1959 Kadison-Singer problem in -algebras is equivalent to fundamental unsolved problems in a dozen areas of research in pure mathema…
The Unconditional Constants for Hilbert Space Frame Expansions
Travis Bemrose, Peter G. Casazza, Victor Kaftal +1
The most fundamental notion in frame theory is the frame expansion of a vector. Although it is well known that these expansions are unconditionally convergent series, no characteri…
The fundamentals of Spectral Tetris frame constructions
Peter G. Casazza, Lindsey M. Woodland
The landmark paper "Constructing tight fusion frames" by Casazza, Fickus, Mixon, Wang and Zhou introduced a fundamental method for constructing unit norm tight frames, which they c…
