Journée-séminaire de combinatoire

(équipe CALIN du LIPN, université Paris-Nord, Villetaneuse)

Le 17 octobre 2017 à 14h00 en B107, Ilya Galanov nous parlera de : On self-assembly of aperiodic tilings

Résumé : Aperiodic tilings serve as a mathematical model for quasicrystals, such crystals that do not have any translational symmetry. Question about how quasicrystals grow still remains open. In this talk I will present the algorithm for growing defect free Penrose tilings using local rules based on paper “Growth rules for quasicrystals” by Joshua Socolar. And state necessary conditions for deterministic growth of cut-and-project aperiodic tilings using “defective seeds".
