任意有限域上椭圆曲线实现的群结构

On group structures realized by elliptic curves over arbitrary finite fields

William D. Banks, Francesco Pappalardi, Igor E. Shparlinski

摘要:

我们研究的收集组结构,可以实现为一组有理点上的椭圆曲线在有限域(这样的群体是众所周知的秩最多为2)。我们还研究了这个集合的各种子集对应的曲线在素域或曲线与规定的挠。我们的一些结果是严格的,是基于解析数论的最新进展,一些条件下,某些广泛认为的假设,和其他纯粹是启发式的性质。

英文摘要:

We study the collection of group structures that can be realized as a group of rational points on an elliptic curve over a finite field (such groups are well known to be of rank at most two). We also study various subsets of this collection which correspond to curves over prime fields or to curves with a prescribed torsion. Some of our results are rigorous and are based on recent advances in analytic number theory, some are conditional under certain widely believed conjectures, and others are purely heuristic in nature.
