有理丢番图三元组诱导的高秩椭圆曲线

High rank elliptic curves induced by rational Diophantine triples

Andrej Dujella, Juan Carlos Peral

摘要:

一个有理丢番图三元组是一个由三个非零有理a,b,c组成的集合,具有ab+1,ac+1,bc+1是完满平方的性质。我们说椭圆曲线y^2 =(ax+1)(bx+1)(cx+1)是由三元组{a,b,c}诱导的。在本文中,我们描述了一个新的方法来构造椭圆曲线在Q上具有合理的高秩的有理丢番图三元组的参数化的基础上。特别地,我们构造了一条秩为12的有理丢番图三元组诱导的椭圆曲线,以及一个秩>= 7的无限族,这两条曲线都是这类曲线的最新记录.

英文摘要:

A rational Diophantine triple is a set of three nonzero rational a,b,c with the property that ab+1, ac+1, bc+1 are perfect squares. We say that the elliptic curve y^2 = (ax+1)(bx+1)(cx+1) is induced by the triple {a,b,c}. In this paper, we describe a new method for construction of elliptic curves over Q with reasonably high rank based on a parametrization of rational Diophantine triples. In particular, we construct an elliptic curve induced by a rational Diophantine triple with rank equal to 12, and an infinite family of such curves with rank >= 7, which are both the current records for that kind of curves.
