Query: Tempered distributions with discrete support and spectrum   We investigate properties of tempered distributions with discrete or
countable supports such that their Fourier transforms are distributions with
discrete or countable supports as well. We find sufficient conditions for
support of the distribution to be a finite union of translations of a full-rank
lattice.
