计算椭圆曲线的3-Selmer群上的Cassels-Tate配对

Computing the Cassels-Tate pairing on the 3-Selmer group of an elliptic curve

Tom Fisher, Rachel Newton

摘要:

本文将计算椭圆曲线的2-Selmer群上Cassels-Tate配对的Cassels方法推广到3-Selmer群上.这需要对计算的局部和全局部分进行重大修改。我们的方法是实用的,在足够小的例子,并可用于提高上限的椭圆曲线的秩由3-下降。

英文摘要:

We extend the method of Cassels for computing the Cassels-Tate pairing on the 2-Selmer group of an elliptic curve, to the case of 3-Selmer groups. This requires significant modifications to both the local and global parts of the calculation. Our method is practical in sufficiently small examples, and can be used to improve the upper bound for the rank of an elliptic curve obtained by 3-descent.
