On dependence of rational points on elliptic curves

Abstract

Let EE be an elliptic curve defined over Q\mathbb Q. Let Γ\Gamma be a subgroup of E(Q)E(\mathbb Q) and PE(Q)P\in E(\mathbb Q). In [1], it was proved that if EE has no nontrivial rational torsion points, then PΓP\in\Gamma if and only if PΓP\in \Gamma mod pp for finitely many primes pp. In this note, assuming the General Riemann Hypothesis, we provide an explicit upper bound on these primes when EE does not have complex multiplication and either EE is a semistable curve or EE has no exceptional prime.
