# Colloquium: Nir Lev (Bar Ilan University) - Fourier quasicrystals

2:30pm to 3:30pm

## Location:

Manchester Building (Hall 2), Hebrew University Jerusalem

By a Fourier quasicrystal we mean a pure point measure in R^d,

whose Fourier transform is also a pure point measure. This notion

was inspired by the experimental discovery of quasicrystalline

materials in the middle of 80's.

The classical example of such a measure comes from Poisson's

summation formula. Which other measures of this type may exist?

I will give the relevant background on this problem and present

our recent results obtained in joint work with Alexander Olevskii.
