Champs de Hurwitz
Antoine Chambert-Loir
Abstract
On construit les champs de Hurwitz et on en donne quelques propriétés, essentiellement contenues dans SGA 1. Quelques applications de nature arithmétique en sont déduites. We propose a construction of Hurwitz stacks and give some properties of them, most of which are consequences of SGA 1. Some applications of arithmetic flavor are then deduced.
