SUMMARY:OS Reelle Geometrie und Algebra: Fourier quasicrystals
DESCRIPTION:A crystalline measure is a tempered distribution with discrete
support whose Fourier transform also has discrete support. Recently\, Pav
el Kurasov and Peter Sarnak answered a question of Yves Meyer by construct
ing crystalline measures on the real line with several desirable propertie
s. The crucial ingredient of their construction are real stable polynomial
s. In the talk I will explain how to generalize their construction using t
he theory of real fibered morphisms and obtain suitable crystalline measur
es in higher dimensions. This is a joint work in progress with Lior Alon\
, Pavel Kurasov and Cynthia Vinzant.
