摘要

在有理函数域上构造了一条扭转群为Z/2Z × Z/4Z且秩为4的椭圆曲线，以及Q上具有相同扭转群且秩为9的椭圆曲线。这两个结果都改进了先前关于该扭转群曲线阶的记录。它们是通过考虑丢番图三元组诱导的椭圆曲线得到的。

High rank elliptic curves with torsion Z/2Z × Z/4Z induced by Diophantine triples

We construct an elliptic curve over the field of rational functions with torsion group Z/2Z × Z/4Z and rank equal to four, and an elliptic curve over Q with the same torsion group and rank nine. Both results improve previous records for ranks of curves of this torsion group. They are obtained by considering elliptic curves induced by Diophantine triples.
