DESCRIPTION:Title: <a href="https://researchseminars.org/talk/OWNS/62/">Sp
 ectral aspects of aperiodic dynamical systems</a>\nby Michael Baake (Unive
 rsität Bielefeld) as part of One World Numeration seminar\n\n\nAbstract\n
 One way to analyse aperiodic systems employs spectral notions\, either via
  dynamical systems theory or via harmonic analysis. In this talk\, we will
  look at two particular aspects of this\, after a quick overview of how th
 e diffraction measure can be used for this purpose. First\, we consider so
 me concequences of inflation rules on the spectra via renormalisation\, an
 d how to use it to exclude absolutely continuous componenta. Second\, we t
 ake a look at a class of dynamical systems of number-theoretic origin\, ho
 w they fit into the spectral picture\, and what (other) methods there are 
 to distinguish them.\n
