Resumen:
Quasicrystals are non-periodic structures discovered by Shechtman in 1984, while he was studying materials whose X-ray diffractions spectra present such nonperiodic behaviors. Nowadays, one of the best mathematical ways to model quasicrystals are the so called model sets introduced by Meyer many years before the discovery of Shechtman. The aim of Meyer was to study approximation of algebraic characters by continuous ones in locally compact abelian groups. Recently, important applications of quasicrystals to Fourier Analysis have been found. In this talk we have discussed some of these applications, making focus in those related with problems of sampling and interpolation in Paley Wiener spaces.
