Abstract

Let X(Γ)X(\Gamma) be the space of all finite Borel measure μ\mu in R2\mathbb R^2 which is supported on the curve Γ\Gamma and absolutely continuous with respect to the arc length of Γ\Gamma. For ΛR2,\Lambda\subset\mathbb R^2, the pair (Γ,Λ)\left(\Gamma, \Lambda\right) is called a Heisenberg uniqueness pair for X(Γ)X(\Gamma) if any μX(Γ)\mu\in X(\Gamma) satisfies μ^Λ=0,\hat\mu\vert_\Lambda=0, implies μ=0.\mu=0. We explore the Heisenberg uniqueness pairs corresponding to the cross, exponential curves, and surfaces. Then, we prove a characterization of the Heisenberg uniqueness pairs corresponding to finitely many parallel lines. We observe that the size of the determining sets Λ\Lambda for X(Γ)X(\Gamma) depends on the number of lines and their irregular distribution that further relates to a phenomenon of interlacing of certain trigonometric polynomials.
