On the Mordell–Weil group of the elliptic curve [formula omitted

Abstract

We study an infinite family of Mordell curves (i.e. the elliptic curves in the form y 2 = x 3 + n , n ∈ Z ) over Q with three explicit integral points. We show that the points are independent in certain cases. We describe how to compute bounds of the canonical heights of the points. Using the result we show that any pair in the three points can always be a part of a basis of the free part of the Mordell–Weil group.
