For let be a subgroup of the Atkin-Lehner involutions of the Drinfeld modular curve . We determine all and for which the quotient curve is rational or elliptic.
Pour désigne un sous-groupe d’involutions d’Atkin-Lehner de la courbe modulaire de Drinfeld. On détermine tous les et tels que la courbe est rationnelle ou elliptique.
