DESCRIPTION:Title: <a href="https://researchseminars.org/talk/DSSUJ/24/">Q
 uasicrystals from the point of view of additive combinatorics</a>\nby Jaku
 b Konieczny as part of Dynamical systems seminar at the Jagiellonian Unive
 rsity\n\nLecture held in 1016.\n\nAbstract\nWe show that some results in a
 dditive combinatorics can\nbe translated into corresponding results that a
 re relevant to the\nmathematical theory of quasicrystals. Specifically\, w
 e will use the\nFreiman–Ruzsa theorem\, characterising finite sets with 
 bounded\ndoubling\, to obtain an alternative proof of a characterisation o
 f\nMeyer sets\, that is\, relatively dense subsets of Euclidean spaces\nwh
 ose difference sets are uniformly discrete.\n
