On the $ℓ^{\infty}$ -norms of the Singular Vectors of Arbitrary Powers of a Difference Matrix with Applications to Sigma-Delta Quantization

Theodore Faust, Mark Iwen, Rayan Saab +1

Let $∥ A ∥_{m a x} := max_{i, j} ∣ A_{i, j} ∣$ denote the maximum magnitude of entries of a given matrix $A$ . In this paper we show that $$\max \left\{ \|U_r \|_{\max},\|V_r\|_{\max}…

Admissible Measurements and Robust Algorithms for Ptychography

Brian Preskitt, Rayan Saab

We study an approach to solving the phase retrieval problem as it arises in a phase-less imaging modality known as ptychography. In ptychography, small overlapping sections of an u…

A direct solver for the phase retrieval problem in ptychographic imaging

Nada Sissouno, Florian Boßmann, Frank Filbir +5

Measurements achieved with ptychographic imaging are a special case of diffraction measurements. They are generated by illuminating small parts of a sample with, e.g., a focused X-…
