Maitreyee Kulkarni (Bonn), Infinite friezes and triangulations of an annulus.
In this talk I will introduce a combinatorial object called a
frieze and describe its relations to triangulations and to representations
of certain quivers. In particular, we will see that each periodic infinite
frieze determines a triangulation of an annulus in a unique way. We will
also study associated module categories and determine an invariant of
friezes in terms of modules. This is joint work with Karin Baur, Ilke
Canakci, Karin Jacobsen, and Gordana Todorov.
