over Q with prescribed local or global behavior by specialization

par Bernat PLANS et N´ uria VILA

R´esum´e. On consid`ere des versions raffin´ees du Probl`eme Inverse de Galois. Nous ´etudions le comportement local et global des sp´ecialisations rationnelles de quelques revˆetements galoisiens finis deP1Q.

Abstract. This paper considers some refined versions of the In- verse Galois Problem. We study the local or global behavior of rational specializations of some finite Galois covers ofP1Q.
