On exponential bases and frames with non-linear phase functions and some applications
Jean-Pierre Gabardo, Chun-Kit Lai, Vignon Oussa
In this paper, we study the spectrality and frame-spectrality of exponential systems of the type where the phase function is a Borel me…
Arbitrarily sparse spectra for self-affine spectral measures
Li-Xiang An, Chun-Kit Lai
Given an expansive matrix and a finite set of digit taken from . It was shown previously that if we can find an suc…
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 , positioned on the axes in ,…
A proof of the Erdös similarity conjecture
Angel Cruz, Chun-Kit Lai, Malabika Pramanik
We show that for any infinite set in , there exists a compact set of positive Lebesgue measure that does not contain any non-trivial affin…
