SUMMARY:Peter Jørgensen (Newcastle)
DESCRIPTION:Title: Coxeter Friezes and p-angulations \nAbstract: A Coxeter frieze is an infinite horizontal array of positive real numbers satisfying a simple local condition. Coxeter friezes were defined in 1971 and have been studied intensively in the past decade\, because they form a nexus between combinatorics\, geometry\, mathematical physics\, and representation theory. \nIt is a classic result by Conway and Coxeter that there is a bijection from triangulations of polygons to Coxeter friezes with entries in the natural numbers. \nThis talk will explain the bijection and show how to generalise it to p-angulations. The generalisation is a joint result with Thorsten Holm (Hannover).
