Abstract:
A doodle is a finite number of closed curves without triple intersections on an oriented surface. There is a “fundamental” group, naturally associated with a doodle. In this paper we study these groups, in particular, we show that fundamental groups of some doodles are automatic and give examples of doodles whose fundamental groups have non-trivial center.References
