Spectral properties of some unions of linear spaces

Chun-Kit Lai, Bochen Liu, Hal Prince

We consider \textit{additive spaces}, consisting of two intervals of unit length or two general probability measures on $R^{1}$ , positioned on the axes in $R^{2}$ ,…

A proof of the Erdös similarity conjecture

Angel Cruz, Chun-Kit Lai, Malabika Pramanik

We show that for any infinite set $A$ in $R$ , there exists a compact set $E \subseteq R$ of positive Lebesgue measure that does not contain any non-trivial affin…

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…

Spark Level Sparsity and the $ℓ_{1}$ Tail Minimization

Chun-Kit Lai, Shidong Li, Daniel Mondo

Solving compressed sensing problems relies on the properties of sparse signals. It is commonly assumed that the sparsity s needs to be less than one half of the spark of the sensin…
