Generators for the elliptic curve y 2 =x 3 -nx
Journal de Théorie des Nombres de Bordeaux, Volume 23 (2011) no. 2, pp. 403-416.

Let E be an elliptic curve given by y 2 =x 3 -nx with a positive integer n. Duquesne in 2007 showed that if n=(2k 2 -2k+1)(18k 2 +30k+17) is square-free with an integer k, then certain two rational points of infinite order can always be in a system of generators for the Mordell-Weil group of E. In this paper, we generalize this result and show that the same is true for infinitely many binary forms n=n(k,l) in [k,l].

Soit E la courbe elliptique définie par y 2 =x 3 -nxn est un entier strictement positif. En 2007, Duquesne a démontré que, pour k entier, si n=(2k 2 -2k+1)(18k 2 +30k+17) est sans facteur carré, alors deux points rationnels spécifiques peuvent toujours se compléter en un système de générateurs du groupe de Mordell-Weil associé à E. Dans ce papier, nous généralisons ce résultat en le montrant pour des entiers n=n(k,l) pour une infinité de formes binaires n(k,l)[k,l].
