小有限域上新的多点曲线

New curves with many points over small finite fields

Karl Rökaeus

摘要:

我们使用类域理论来搜索小有限域上具有许多有理点的曲线。通过对小亏格曲线的阿贝尔覆盖的研究,我们发现了一些新的曲线。特别地,我们通过找到一条有18个点的曲线来解决GF(2)上亏格为17的曲线可以有多少个点的问题。搜索是由计算机辅助的;在某些情况下,它是详尽的这种类型的曲线的属高达50。

英文摘要:

We use class field theory to search for curves with many rational points over small finite fields. By going through abelian covers of curves of small genus we find a number of new curves. In particular, we settle the question of how many points a curve over GF(2) of genus 17 can have, by finding one with 18 points. The search is aided by computer; in some cases it is exhaustive for this type of curve of genus up to 50.
