Abstract

A Heisenberg uniqueness pair is a pair (Γ,Λ)\left(\Gamma, \Lambda\right), where Γ\Gamma is a curve and Λ\Lambda is a set in R2\mathbb R^2 such that whenever a finite Borel measure μ\mu having support on Γ\Gamma which is absolutely continuous with respect to the arc length on Γ\Gamma satisfies μ^Λ=0,\hat\mu\vert_\Lambda=0, then it is identically 0.0. In this article, we investigate the Heisenberg uniqueness pairs corresponding to the spiral, hyperbola, circle and certain exponential curves. Further, we work out a characterization of the Heisenberg uniqueness pairs corresponding to four parallel lines. In the latter case, we observe a phenomenon of interlacing of three trigonometric polynomials.
