Query: Crystalline temperate distributions with uniformly discrete support and
  spectrum   We prove that a temperate distribution on $\mathbb{R}$ whose support and
spectrum are uniformly discrete sets, can be obtained from Poisson's summation
formula by a finite number of basic operations (shifts, modulations,
differentiations, multiplication by polynomials, and taking linear
combinations).
