Abstract

AbstractLet K be a number field, an algebraic closure of K and E/K an elliptic curve defined over K. In this paper, we prove that if E/K has a K-rational point P such that 2P ≠ O and 3P ≠ O, then for each σ ∈ Gal(/K), the Mordell–Weil group of E over the fixed subfield of under σ has infinite rank.
