Involutory elliptic curves over 𝔽 q (T)
Journal de théorie des nombres de Bordeaux, Tome 10 (1998) no. 1, pp. 107-123

For n∈𝔽 q [T] let G be a subgroup of the Atkin-Lehner involutions of the Drinfeld modular curve X 0 (𝔫). We determine all 𝔫 and G for which the quotient curve G∖X 0 (𝔫) is rational or elliptic.

Pour 𝔫∈𝔽 q [T],G désigne un sous-groupe d’involutions d’Atkin-Lehner de la courbe modulaire X 0 (𝔫) de Drinfeld. On détermine tous les 𝔫 et G tels que la courbe G∖X 0 (𝔫) est rationnelle ou elliptique.
