DESCRIPTION:Speakers: Justin Kulp (Perimeter Institute\, Waterloo & IHES)\
 n\nMost people are familiar with periodic tessellations and lattices\; fro
 m the patio floor at the reception building to their favourite spin system
 s. In this talk\, I will discuss two less familiar families of tessellatio
 ns and their possible connections to high energy physics\, condensed matte
 r physics\, and mathematics: hyperbolic tessellations and quasicrystals. 
 After introducing the basics of regular hyperbolic lattices\, I will surve
 y constructions and surprising properties of quasicrystals (like the Pen
 rose tiling)\, including their classically forbidden symmetries\, long-ran
 ge order\, and self-similar structure. Inspired by the AdS/CFT corresponde
 nce\, I will describe a mathematical relationship between hyperbolic latti
 ces in (D+1)-dimensions and quasicrystals in D-dimensions\, as well as t
 he resolution of a conjecture by Bill Thurston. Based on work to appear w
 ith Latham Boyle. Pour être informé des prochains séminaires vous pouv
