Martin-Deschamps, Mireille
Propriétés de descente des variétés à fibré cotangent ample.
(French)
[J] Ann. Inst. Fourier 34, No.3, 39-64 (1984). ISSN 0373-0956; ISSN 1777-5310/e

On généralise ici un théorème de Grauert-Manin pour les courbes (problème de Mordell pour les corps de fonctions). Soit L un corps de fonctions algébriques sur un corps algébriquement clos k de caractéristique 0, X une variété propre et lisse sur L, dont le fibré cotangent $\Omega\sp 1\!\sb{X/L}$ est ample; si l'ensemble de ses points rationnels est Zariski-dense, la variété X se redescend sur k.
