摘 要:A dessin is a 2-cell embedding in an orientable surface of a bipartite graph.Dessins play important roles in the study
of algebraic curves, and surface topology. I will report on recent progress of edge-transitive dessins; in particular, I
will present some interesting applications to surface coverings.
