> Title: On Infinite Dessins
>
> Abstract: The first hour of the lecture will be reserved for elementary
> aspects of Grothendieck's theory of dessins d'enfants. Precisely, we will
> explain how uniformization and Fuchsian groups enter the picture. In the
> second part, the plan is to spend some time on the cosine function, and
> then
> desribe two more transcendental functions which are closely related to
> combinatorial objects. If time permits, a certain ball quotient will be
> described, whose certain compactification in a natural way contains the
> combinatorial objects used to define transcendental functions.
