Injectivity of the specialization homomorphism of elliptic curves

Ivica Gusić, Petra Tadić

Let $E : y^{2} = x^{3} + A x^{2} + B x + C$ be a nonconstant elliptic curve over $Q (t)$ with at least one nontrivial $Q (t)$ -rational $2$ -torsion point. We describe a method for fin…

Injectivity of the specialization homomorphism of elliptic curves

Ivica Gusic, Petra Tadic

Let $E : y^{2} = (x - e_{1}) (x - e_{2}) (x - e_{3})$ be a nonconstant elliptic curve over $Q (t)$ , where $e_{j} \in Z [t]$ . We describe a method for finding a specialization $t\mapsto t_…
