 Title: Hyperbolic geometry of friezes

Abstract:

  Frieze patterns were introduced by Coxeter in the 1970s who, with Conway, established a correspondence between frieze patterns and triangulated polygons. It turned out later that this object is very rich in connections with different fields in mathematics. We use hyperbolic geometry to provide a classification of positive integral friezes on marked bordered surfaces. This is a joint work with Pavel Tumarkin.
