1 6 Ju n 20 06 QUADRATIC TWISTS OF PAIRS OF ELLIPTIC CURVES

Abstract

Given two elliptic curves defined over a number field K, not both with jinvariant zero, we show that there are infinitely many D ∈ K with pairwise distinct image in K/K 2 , such that the quadratic twist of both curves by D have positive Mordell-Weil rank. The proof depends on relating the values of pairs of cubic polynomials to rational points on another elliptic curve, and on a fiber product construction.
