SUMMARY:Michael Baake (Universität Bielefeld): Dynamical systems of number
 -theoretic origin in the theory of aperiodic order
DESCRIPTION:Michael Baake: Cut and project sets\, which go back to Yves Mey
 er (1972) in mathematics and to Peter Kramer (1982) in physics\, are a ver
 satile class of structures with amazing harmonic properties. These sets ar
 e also known as mathematical quasicrystals\, and include the famous Penros
 e tiling with fivefold symmetry as well as its various generalisations to 
 other non-crystallographic symmetries. These constructions are widely used
  to model the structures discovered in 1982 by Dan Shechtman (2011 Nobel L
 aureate in Chemistry). More recently\, also systems such as the square-fre
 e integers or the visible lattice points have been studied in this context
 \, leading to the theory of weak model sets. This talk will review some of
  the developments\, and introduce important concepts of the field\, with f
 ocus on spectral aspects.\nSlides: http://eventos.cmm.uchile.cl/ir2016/wp-
