Structured coordinate systems in $L^{p} (R)$

Daniel Freeman, Lukas Liehr, Mitchell A. Taylor

We construct Schauder bases of $L^{p} (R)$ with significant structural constraints on their elements. First, we construct non-negative Schauder bases of $L^{p} (R)$ for…

The Cahill-Casazza-Daubechies problem on Hölder stable phase retrieval

Daniel Freeman, Mitchell A. Taylor

Phase retrieval using a frame for a finite-dimensional Hilbert space is known to always be Lipschitz stable. However, phase retrieval using a frame or a continuous frame for an inf…
