If you have a question about this talk, please contact David Craven. The theory of dessins d’enfants is based on the equivalence of a certain combinatorial-topological category (of graphs on compact oriented surfaces) and an arithmetico-geometric one (of algebraic curves over number fields together with special rational functions on them). The objects of both categories admit a group-theoretic description as well. The talk will start with a brief introduction to the theory. After that the group-theoretic aspects of it will be discussed, basically related to a certain graphic images of 2-generated groups and to the Inverse Galois Problem. Some examples will be presented and the lines of research suggested.
