This book grew out of a workshop on the applications of moduli spaces of Riemann surfaces in theoretical physics and number theory and on Grothendieck's dessins d'enfants and their generalizations. Chapter 1 gives an introduction to Teichmuller space that is more concise than the popular textbooks, yet contains full proofs of many useful results which are often difficult to find in the literature. This chapter also contains an introduction to moduli spaces of curves, with a detailed...
Beginning with an introduction to Teichmüller space and the moduli spaces of curves, this book gives a complete description of the genus zero moduli spaces and their fundamental groupoids and then goes on to use other Grothendieck-Teichmüller theory to compute a study of the canonical Galois action on the fundamental groupoids.
