Abstract
We give a parameterization of the algebraic points of degree \(\le 3\) over \(\mathbb {Q}\) on the curve \( y^{2}=x^{5}+1. \) This result extends a previous result of Schaefer who described in Schaefer (Math Ann 310:447–471, 1998) the set of algebraic points of degree \(\le 2 \) over \(\mathbb {Q}\).
Résumé
Nous donnons une paramétrisation des points algébriques de degré au plus 3 sur \(\mathbb {Q}\) sur la courbe \(\mathcal {C} \) d’équation affine: \( y^{2}=x^{5}+1 \). L’énoncé obtenu étend un résultat de Schaefer qui décrivait dans Schaefer (Math Ann 310:447–471, 1998) l’ensemble des points algébriques de degré au plus 2 sur \(\mathbb {Q}\) sur cette courbe.
