The spectrality of symmetric additive measures
Comptes Rendus. Mathématique, Volume 361 (2023), pp. 783-793.

Let ρ be a symmetric measure of Lebesgue type, i.e.,

ρ=1 2(μ×δ 0 +δ 0 ×μ),

where the component measure μ is the Lebesgue measure supported on [t,t+1] for t{-1 2} and δ 0 is the Dirac measure at 0. We prove that ρ is a spectral measure if and only if t1 2. In this case, L 2 (ρ) has a unique orthonormal basis of the form

e 2πi(λx-λy) :λΛ 0 ,

where Λ 0 is the spectrum of the Lebesgue measure supported on [-t-1,-t][t,t+1]. Our result answers some questions raised by Lai, Liu and Prince [JFA, 2021].
