Conjugate Phase Retrieval in Paley-Wiener Space

Chun-Kit Lai, Friedrich Littmann, Eric Weber

We consider the problem of conjugate phase retrieval in Paley-Wiener space $P W_{π}$ . The goal of conjugate phase retrieval is to recover a signal $f$ from the magnitudes of linear me…

Spectrum is rational in dimension one

Chun-Kit Lai, Yang Wang

A bounded measurable set $Ω \subset R^{d}$ is called a spectral set if it admits some exponential orthonormal basis ${e^{2 π i ⟨ λ, x ⟩} : λ \in Λ}$ for $L^{2} (Ω)$ . In th…

Fourier frames for surface-carried measures

Alex Iosevich, Chun-Kit Lai, Bochen Liu +1

In this paper we show that the surface measure on the boundary of a convex body of everywhere positive Gaussian curvature does not admit a Fourier frame. This answers a question pr…

On Spectral Cantor-Moran measures and a variant of Bourgain's sum of sine problem

Li-Xiang An, Xiaoye Fu, Chun-Kit Lai

In this paper, we show that if we have a sequence of Hadamard triples ${(N_{n}, B_{n}, L_{n})}$ with $B_{n} \subset {0, 1, .., N_{n} - 1}$ for $n = 1, 2, ...$ , except an extreme case, then the assoc…
